Percutaneous transabdominal puncture of the uterus during pregnancy to obtain amniotic fluid. It is commonly used for fetal karyotype determination in order to diagnose abnormal fetal conditions.
A clear, yellowish liquid that envelopes the FETUS inside the sac of AMNION. In the first trimester, it is likely a transudate of maternal or fetal plasma. In the second trimester, amniotic fluid derives primarily from fetal lung and kidney. Cells or substances in this fluid can be removed for prenatal diagnostic tests (AMNIOCENTESIS).
A method for diagnosis of fetal diseases by sampling the cells of the placental chorionic villi for DNA analysis, presence of bacteria, concentration of metabolites, etc. The advantage over amniocentesis is that the procedure can be carried out in the first trimester.

Pathophysiological conditions of the FETUS in the UTERUS. Some fetal diseases may be treated with FETAL THERAPIES.
A chromosome disorder associated either with an extra chromosome 21 or an effective trisomy for chromosome 21. Clinical manifestations include hypotonia, short stature, brachycephaly, upslanting palpebral fissures, epicanthus, Brushfield spots on the iris, protruding tongue, small ears, short, broad hands, fifth finger clinodactyly, Simian crease, and moderate to severe INTELLECTUAL DISABILITY. Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE.

Adrenomedullin production is increased in normal human pregnancy. (1/368)

OBJECTIVE: Adrenomedullin, a recently discovered vasoactive peptide originally identified in pheochromocytoma, has been found to be increased in the plasma of pregnant women at term. This study was designed to elucidate whether adrenomedullin secretion is dependent on gestational age and the possible source and function of this peptide in human pregnancy. STUDY DESIGN: Adrenomedullin concentrations were determined by RIA in amniotic fluid and maternal plasma obtained from 110 pregnant women between 8 and 40 weeks of gestation. Subjects were stratified into five groups according to gestational age. In term patients (n = 15), adrenomedullin was also measured in the umbilical artery and vein separately. RESULTS: High concentrations of adrenomedullin were present in plasma and amniotic fluid samples from patients in the first, second and third trimester. There was no significant difference in mean maternal plasma concentration of adrenomedullin between the five patient groupings. Amniotic fluid adrenomedullin concentrations decreased from 81.2 +/- 11.7 pg/ml at 8-12 weeks of gestation to 63.7 +/- 6.0 pg/ml at 13-20 weeks of gestation and then increased at 21-28 weeks of gestation to 99.1 +/- 10.4 pg/ml. A further increase was found in samples collected after 37 weeks of gestation (132.6 +/- 10.1 pg/ml). In the umbilical vein, adrenomedullin concentration was higher (P < 0.05) than in the artery (65.7 +/- 6.1 pg/ml and 48.5 +/- 5.2 pg/ml respectively), suggesting that adrenomedullin in the fetal circulation derives from the placenta. CONCLUSIONS: Our results demonstrate the presence of adrenomedullin in maternal plasma and amniotic fluid throughout gestation, and show that its production starts very early in gestation, suggesting that this hormone may have an important role in human reproduction, from implantation to delivery.  (+info)

Mosaic trisomy 17 in amniocytes: phenotypic outcome, tissue distribution, and uniparental disomy studies. (2/368)

Mosaicism for trisomy 17 in amniocyte cultures is a rare finding, whilst postnatal cases are exceptional. In order to gain insight into the possible effects of the distribution of the trisomic line and of uniparental disomy (UPD) on embryofoetal development, we have performed follow-up clinical, cytogenetic and molecular investigations into three newly detected prenatal cases of trisomy 17 mosaicism identified in cultured amniotic fluid. In the first case, the pregnancy ended normally with the birth of a healthy girl, and analysis of newborn lymphocytes and of multiple extra-embryonic tissues was indicative of confined placental mosaicism. The second case was also associated with a normal pregnancy outcome and postnatal development, and only euploid cells were found in peripheral blood after birth. However, maternal isodisomy 17 consequent to a meiosis II error and loss of a chromosome 17 homologue was detected in peripheral lymphocytes postnatally. In the third case, pathological examination after termination of pregnancy showed growth retardation and minor dysmorphisms, and the trisomic line was detected in foetal skin fibroblasts. In addition, biparental derivation of chromosome 17 was demonstrated in the euploid lineage. These results, together with previously reported data, indicate that true amniotic trisomy 17 mosaicism is more commonly of extra-embryonic origin and associated with normal foetal development. Phenotypic consequences may arise when the trisomic line is present in foetal tissues. Case 2 also represents the first observation of maternal UPD involving chromosome 17; the absence of phenotypic anomalies in the child suggests that chromosome 17 is not likely to be subject to imprinting in maternal gametes.  (+info)

Collagenous constituents of amniotic fluid. (3/368)

The amniotic fluid (AF) was fractionated by dialysis, gel filtration and SDS/PAGE, and submitted to the assay of collagenous constituents. The collagenous character of peptides and proteins of amniotic fluid was confirmed by hydroxyproline (Hyp) assay and treatment with bacterial collagenase followed by electrophoresis and gel filtration of the digestion products. It was found that AF contains collagen degradation products but the classical method of Hyp determination described by Woessner (Arch. Biochem. Biophys., 1961, 93, 440-447) gives overestimated values due to the interference with other AF components. Fractionation of AF on Sephadex G-100 column allowed to remove the interfering material and to estimate the actual Hyp content which equals to approx. 6.2 microg/ml. About 70% of Hyp was found in low molecular dialyzable products and the rest (about 30%) appears to be a constituent of nondialyzable collagenous polypeptides of the molecular mass of about 7.9-26.3 kDa. It is suggested that such collagenous polypeptides may be the products of proteolytic conversion of collagen precursor (procollagen) into the monomeric form of this protein. No high molecular forms of collagen, corresponding to alpha-subunits, were found.  (+info)

Prenatal diagnosis of spinal muscular atrophy type I (Werdnig- hoffmann) by DNA deletion analysis of cultivated amniocytes. (4/368)

AIM: Presentation of a prenatally diagnosed case of Werdnig-Hoffmann disease, the most severe type of spinal muscular atrophy. METHODS: DNA obtained from cultivated amniocytes was analyzed for deletions in the survival motor neuron gene and neuronal apoptosis inhibitory protein gene. RESULTS: The fetus was diagnosed as an affected homozygote for deletions in exon 7 and exon 8 of the survival motor neuron gene. No deletions of exon 5 in the neuronal apoptosis inhibitory protein gene were found. CONCLUSION: Direct DNA deletion analysis of the survival motor neuron gene and neuronal apoptosis inhibitory protein gene in affected families represents a highly reliable and fast method for prenatal diagnosis of Werdnig-Hoffmann disease.  (+info)

Prenatal confirmation of the translocation between chromosome 15 and Y-chromosome by fluorescence in situ hybridization. (5/368)

The karyotype was 46, XX, 15, der (15) t (Y; 15) (q12; p12) pat. ish der (15) (DYZ1+). A female baby was delivered. The growth of the baby was normal at 12 months of age.  (+info)

Second-trimester maternal urine human chorionic gonadotrophin beta-core fragment concentrations in Asian pregnancies with fetal chromosomal abnormalities. (6/368)

The aim of this study was to investigate the second trimester concentrations of maternal urine human chorionic gonadotrophin beta-core fragment (HCGbetacf) in Asian pregnanci2es with fetal chromosomal abnormalities. HCGbetacf concentrations were analysed from 34 urine samples in chromosomally abnormal pregnancies, including 28 cases of Down's syndrome, one case of trisomy 18, and five cases of other chromosomal abnormalities (one mosaic deletion and four translocations), and in a cohort of 268 normal pregnancies receiving second trimester amniocentesis. Results were normalized to urine creatinine (Cr) concentration and converted to the multiple of the median (MOM) concentration for the appropriate gestation. The median HCGbetacf MOM concentrations of Down's syndrome pregnancies (12.89) was significantly higher than that of normal pregnancies (1. 06) (P < 0.00001). Wide variations of HCGbetacf concentrations were observed in other chromosomally abnormal pregnancies. There were 18 of 28 (64%) Down's syndrome cases but one of five (20%) other chromosomally abnormal cases with HCGbetacf concentrations above the 95th centile of the control values (8.22 MOM cut-off). These findings suggest that HCGbetacf could be a potential marker in urine screening for fetal Down's syndrome in Asians.  (+info)

Prenatal diagnostic and prognostic value of human cytomegalovirus load and IgM antibody response in blood of congenitally infected fetuses. (7/368)

Human cytomegalovirus (HCMV) load and virus-specific IgM were quantified in blood of 36 fetuses from mothers with primary HCMV infection. Nineteen fetuses were congenitally infected and 17 were uninfected as diagnosed by virus isolation from and DNA detection in amniotic fluid. Sensitivity of antigenemia was 57.9%; of viremia, 55. 5%; of leukoDNAemia, 82.3%; and of IgM, 57.9%; specificity was 100% for all assays. When amniocentesis was performed, 4 HCMV-infected fetuses (group A) showed abnormal ultrasound and biochemical/hematologic findings, 8 (group B) had elevated gamma-glutamyl transferase values, and 7 (group C) had normal ultrasound and biochemical findings. Virus loads were higher in groups A and B than in group C. In group A, no pregnancy went to term, in group B, 3 of 6 newborns were symptomatic at birth, and in group C, the 6 newborns were subclinically infected. Taken together, virologic, laboratory, and ultrasound findings may contribute to a better prognostic definition of fetal HCMV infection.  (+info)

Role of multicolor fluorescence in situ hybridization (FISH) in simultaneous detection of probe sets for chromosome 18, X and Y in uncultured amniotic fluid cells. (8/368)

Major aneuploidies diagnosed prenatally involve the autosomes 13, 18, and 21, and sex chromosomes. Fluorescence in situ hybridization (FISH) allows rapid analysis of chromosome copy number in interphase cells. The purpose of this study was to evaluate the role of multicolor fluorescence in situ hybridization in simultaneous detection of probe sets for chromosome 18, X, and Y in uncultured amniotic fluid cells as a safer alternative method for aneuploidy detection prenatally. Fifty amniotic fluid samples were analyzed by FISH and standard cytogenetics. Mean time to obtain results was three days for fluorescence in situ hybridization and 20 days for karyotype. Fluorescence in situ hybridization was informative in 43 samples (86%), and within this group, two aneuploidies were correctly identified. This evaluation demonstrates that FISH with X, Y, and 18 alpha satellite DNA probes could accurately and rapidly detect aneuploidies involving these chromosomes and could be used in any prenatal clinical laboratory.  (+info)

An amniocentesis is a procedure used to obtain a small sample of the amniotic fluid that surrounds the fetus to diagnose chromosomal disorders and open neural tube defects (ONTDs) such as spina bifida. Testing is available for other genetic defects and disorders depending on the family history and availability of laboratory testing at the time of the procedure. An amniocentesis is generally offered to women between the 15th and 20th weeks of pregnancy who are at increased risk for chromosome abnormalities, such as women who are over age 35 years of age at delivery, or those who have had an abnormal maternal serum screening test, indicating an increased risk for a chromosomal abnormality or neural tube defect.. ...

Most of them use samples from foetuses collected after legal interruption of pregnancy. In some cases, a control population is needed and foetuses aborted for non-chromosomal reasons are used. The assumption of these samples as being euploids could perhaps represent an error. In this article, we describe an easy methodology to certify the euploidy of foetal ovarian tissue using an one-week somatic culture. Using this protocol, we have obtained a primary culture in 88.2% of the studied cases, material usable for being karyotyped in 93.3% of the cases, and a cytogenetic diagnosis was performed in 100% of these cases. Finding the same karyotype ...
During the period from 1 January 1996 to 31 December 1999, 2378 women had amniotic fluid analysed for aneuploidy based on a positive maternal serum triple test (risk for trisomy 21, or = 1/250). In Belgium, triple test screening is routinely offered to all pregnant women. These samples were analysed at the Leuven Centre for Human Genetics and showed normal chromosome results and normal amniotic fluid alpha-fetoprotein. These samples did not include the samples analysed in the previous study between 1 January 1993 and 31 December 1995.. Maternal serum triple tests and amniocenteses were performed in different centres. In February 2001, a questionnaire (available on request) was mailed to the 2378 women with a list of questions about the outcome of pregnancy, the perinatal history, and the physical and psychomotor development of their children. In this questionnaire, parents also answered if a fetal malformation was diagnosed prenatally and if pregnancy was interrupted; 265 questionnaires were ...
This information leaflet is for pregnant women who are offered a chorionic villus sampling (CVS) or amniocentesis diagnostic test.
In pregnancies complicated by red cell alloimmunization, the fetus may suffer from chronic progressive hemolytic anemia. Severe fetal anemia leading to hydrops and fetal demise can occur as early as 17 weeks gestation, while in other pregnancies the only manifestation of the disease is neonatal hyperbilirubinemia. The standard of care in the management of these pregnancies is to select patients at risk of fetal anemia using information about their obstetric history, and serial maternal serum antibody measurements. The selected patients are followed closely, usually in referral centers with a special interest and expertise in managing this now relatively rare disease. Ultrasound evaluation of fetal condition, with emphasis on signs of fetal hydrops, is performed regularly. In addition, serial amniocentesis is done to assess amniotic fluid bilirubin (deltaOD450) values. This spectrophotometric method estimates the level of bilirubin in the amniotic fluid, which correlates with the severity of the ...
The fetal cells, chemicals, and microorganisms surrounding the fetus provide a wide range of information regarding your childs genetic makeup. Amniocentesis involves extracting and examining these things in order to determine if your baby has a chromosomal abnormality as wekk as his fetal lung maturity.
Amniocentesis is a test that can reveal certain fetal abnormalities. Amniotic fluid is obtained for study from the fluid surrounding the fetus. The amniotic fluid must be withdrawn by needle. Ultrasound is used to locate a pocket of fluid where the fetus and placenta are out of the way. Skin over the abdomen is cleaned and numbed with a local anesthetic. A long needle is then passed through the abdomen into the uterus, and fluid is withdrawn from the uterus with a syringe ...

Amniocentesis is used to obtain genetic information about a developing fetus by collecting a sample of amniotic fluid, the fluid that cushions a baby inside the mothers uterus. This fluid contains cells. When studied in a laboratory, these cells can tell physicians if certain genetic conditions are present in the baby. A doctor may recommend an amniocentesis because of advanced maternal age (usually 35 or older) or because other prenatal screenings may have revealed a risk that the baby has an inherited or congenital condition. Amniocentesis can also be used to test the fluid for signs of fetal infection, or later in the pregnancy to evaluate the maturity of the babys lungs.. During the test, a thin needle is placed into the mothers abdomen in order to collect a sample of amniotic fluid which can then be sent for genetic testing. The needle is carefully placed with the help of ultrasound guidance.. Risks: Any diagnostic procedure carries some risk. Your physician will explain the test and ...
As a Maternal Fetal Medicine specialist - a physician who takes care of high risk pregnancies and provides prenatal diagnosis such as amniocentesis, I take issue with the comments posted here and elsewhere that Gov. Palin must have considered the option of abortion if she had an amniocentesis. While it is true that many parents who feel that abortion is not an option decline invasive testing like amniocentesis, there are also many others who choose to go ahead with it, for a variety of reasons. The primary reason from the patients point of view is that the small risk of miscarriage (currently believed to be 1//750-1/1600) is worth the advantage of knowing information ahead of time to become prepared. Upon first learning of the diagnosis most, if not all, parents will go through intense grief, and then will come to accept the diagnosis. Prenatal testing allows the patient and her family to deal with their grief before the baby arrives, and then experience joy at the time of the birth, rather ...

The biggest challenge I think I faced while my wife was pregnant was making the decision to forgo amniocentesis in the second trimester. My wife and I were both 43 years old when she became pregnant with our son. There was some consideration about doing an amniocentesis because of her age, just to make sure everything was okay.. We decided that there was nothing that we were going to do differently, if say, an amniocentesis were to show a genetic abnormality. We felt lucky and blessed to be expecting a child and simply chose to have faith that he or she would be born healthy. The challenge for me, as a physician, was in making the decision not to rely on an invasive test, which held some risk, of the possibility of losing the pregnancy. Our son was a breach baby and we were informed that a small percentage of breach babies have some underlying abnormality, which is associated with the fact that ...
Your health care provider may discuss amniocentesis with you if youre older than 35 or if your screening tests indicated that there may be a problem with the fetus. Amniocentesis is a test usually done between 15 and 18 weeks that can detect abnormalities in a fetus, such as Down syndrome.. During this test, a very thin needle is inserted into the amniotic fluid surrounding the baby to take a sample of the fluid for analysis. Amniocentesis does carry a very slight risk of miscarriage, so talk to your health care provider about your concerns and the risks and advantages of the test.. ...
One of the most advanced prenatal diagnosis methods to date, the amniocentesis test is used to detect particular chromosomal abnormalities and serious birth defects, and involves the extraction of a sample of the amniotic fluid surrounding the fetal cells for detailed laboratory examination. It is usually conducted if a previous screening test indicated a high possibility of fetal abnormality; the mother is over 35 years of age; either the mother or both parents are carriers of genetic or recessive inherited disorders; a fetal infection is suspected; or it is necessary to examine the fetuss lung maturity late in pregnancy. This test can be conducted as early as the 13th week or as late as the 24th week based on its necessity, and the results need 10 to 14 days to be formulated and released. The amniocentesis test is both extremely accurate and entirely safe ...
Back in the day the only option to evaluate these conditions was an amniocentesis. This procedure is still done today as a last measure diagnostic of chromosomal abnormalities and neural tube defects. Nowadays before a women gets to that, there are a number of less invasive tests that can be done to assess the risk that the baby isnt healthy. Now the key phrase is to assess the risk thats all these early blood tests and fetal ultrasounds can do, risk assessment- they are not a diagnosis. An amniocentesis is the only test that provides a diagnosis. Women nowadays have the option of taking a blood test in the first trimester along with a detailed ultrasound, or waiting until the second trimester to take a different blood test. Physicians will make recommendations on which (if any) time point makes more sense for a given women, strongly dependent on her age but also her family history and personal history as well. If a women is over 30 these tests are explained early on by her doctors, and ...

A technique for testing the genetic health of a fetus by inserting a needle through the mothers abdominal wall into the uterus and extracting a small amount of the amniotic fluid, the fluid that surrounds the fetus. Sloughed-off fetal cells (fibroblasts) found in this fluid are then cultured and their DNA examined for defects. This procedure is done in the second trimester, and because of the time needed to do the culture, results arent generally available until after the 20th week of pregnancy ...

First, your health care provider will use ultrasound to determine the babys exact location in your uterus. Youll lie on your back on an exam table and expose your abdomen. Your health care provider will apply a special gel to your abdomen and then use a small device known as an ultrasound transducer to show your babys position on a monitor.. Next, your health care provider will clean your abdomen with an antiseptic. Generally, anesthetic isnt used. Most women report only mild discomfort during the procedure.. Guided by ultrasound, your health care provider will insert a thin, hollow needle through your abdominal wall and into the uterus. A small amount of amniotic fluid will be withdrawn into a syringe, and the needle will be removed. The specific amount of amniotic fluid withdrawn depends on the number of weeks the pregnancy has progressed.. Youll need to lie still while the needle is inserted and the amniotic fluid is withdrawn. You might notice a stinging sensation when the needle enters ...
This is your Pea in the Podcast for week 17 of your pregnancy. Im Bonnie Petrie joined by Dr. Laurie Swaim, an obstetrician with Houston Womens Care Associates in Houston, Texas.. Sometime between now and week 20 your baby will begin to hear. So now he or she will hear all of those long conversations youve been having with them, all those sweet songs youve been singing. Your baby will recognize and respond to your voice after birth so talk away. In fact, the world your baby gets used to hearing in the womb is pretty noisy, between your voice and your heartbeat, blood flow and breathing, some babies will have trouble getting used to the relative quiet outside after theyre born and will need to have some white noise playing in the background in order to get any sleep as they acclimate to life in the world. There is some evidence though that fetal exposure to noise that is too loud, so loud you have to speak loudly to be understood, well it could damage their developing hearing so be careful ...
But heres the rub vis a vis Gov. Palin. We are being told that she did do the test and then, what? Well, ... nothing. From all appearances, she IGNORED the results. She continued to plan to give birth with a family practice doctor who practices 800 miles from Palins (supposed) primary residence. She continued to plan to give birth in a small rural / community hospital with no NICU, even though about 30% of Downs babies have some sort of heart problem and some need surgery right after birth. She got ON an airplane at 35-36 weeks pregnant with a KNOWN HIGH RISK pregnancy to travel thousands of miles to GIVE A SPEECH and then got back on the plane when her membranes began leaking and traveled approximately 12 hours back to Alaska. She apparently needed months to get used to the fact that she was going to have the responsibility for a special needs child, but didnt bother to prepare her older children at all. And if all of this is not enough, were to believe that a physician went along with ...
The ability of the early intrauterine environment to program fetal neurodevelopment has been documented in several species, and there is evidence to suggest that a similar process may occur in humans. Glucocorticoids are the primary candidates for fetal hypothalamic-pituitary-adrenal (HPA) programming, but testosterone and DHEAS may also be involved. This thesis examines the relationship between these amniotic fluid honnones, particularly in the context of prenatal stress. Human studies lack the precision of animal experimental paradigms, and most stress protocols in humans have involved laboratory stressors poorly standardised for duration and nature of exposure. I aimed to use a standardised clinical stressor to examine the endocrine response in maternal plasma and amniotic fluid. I hypothesised that amniocentesis in a clinical setting elicits a maternal stress response associated with alterations in amniotic fluid steroidal hormones. I found amniocentesis to be associated with raised ...

  • Amniocentesis is a procedure in which a small amount of amniotic fluid is withdrawn from the amniotic sac and sent to a laboratory for evaluation. (
  • Testing can also be done by amniocentesis after 16 weeks gestation by removing a small amount of the amniotic fluid surrounding the baby and analyzing the cells in the fluid. (
  • An amniocentesis may be performed in which fetal cells are removed from the amniotic fluid and enzyme activity is measured. (
  • Amniocentesis (sampling amniotic fluid) between 20 and 24 weeks of gestation can detect toxoplasmosis in the fetus. (
  • Amniocentesis is an invasive prenatal procedure in which a small amount of amniotic fluid is extracted from your baby's amniotic fluid to check your baby for chromosomal disorders. (
  • When you undergo amniocentesis, a 4-inch, 22-gauge needle will be pushed through your abdominal wall, through your uterus, chorion, and amniotic sack into the amniotic fluid. (
  • Later in your pregnancy, amniocentesis may also be used to determine fetal lung function, to identify possible fetal lung infections, or the presence of too much amniotic fluid (polyhydramnios). (
  • Demand for the amniocentesis needles is expected to gain momentum attributed to growing need for removing excessive amniotic fluid from around the baby. (
  • Prevalence of placental tumor and gestational diabetes also leads to an excess of amniotic fluid, which is further expected to contribute towards growth of the global amniocentesis needles market during the forecast period. (
  • As the requirement to remove the excess of amniotic fluid continues to increase, preference to use amniocentesis needles of 100-150 mm length is projected to remain high. (
  • To test amniotic fluid, an amniocentesis is done. (
  • During amniocentesis amniotic fluid is collected for prenatal diagnosis to identify any genetic abnormality, fetal infection and neural tube defects occurring during pregnancy ensuring optimum health to both the developing fetus and mother. (
  • Amniocentesis refers to the removal of amniotic fluid by placing a needle into the amniotic cavity under ultrasound guidance. (
  • In order to perform amniocentesis, a needle must be inserted into the mother's abdomen to extract amniotic fluid. (
  • For the patient the procedure has not changed - an amniocentesis is still needed to collect the amniotic fluid, which is only recommended in pregnant women at risk for carrying a fetus with a syndrome. (
  • If the participants note that they will be receiving an amniocentesis in connection with their clinical care, the research team will arrange with the participant and her obstetrician to obtain a sample of the amniotic fluid to test for Zika infection. (

  • An amniocentesis is offered between the 15th and 20th weeks of pregnancy to those who are at greater risk for birth defects. (
  • The risk of miscarriage is considered less than 1% after an amniocentesis in the second trimester of pregnancy. (
  • In later pregnancy, the bladder should be empty to lower the risk of puncture with the amniocentesis needle. (
  • Pregnancy: Should I Have Amniocentesis? (
  • Amniocentesis is a known cause of concerns among expectant mothers as it is associated with the risk of pregnancy loss. (
  • Although it is true that this invasive diagnostic test during pregnancy carries a 1% risk of miscarriage, an amniocentesis is generally a safe and relatively painless procedure that can be an important in tool in monitoring fetal well-being , especially in women with known risk factors for having a child with genetic disorders or positive screening tests. (
  • Amniocentesis is a test you may be offered during pregnancy to check if your baby has a genetic or chromosomal condition, such as Down's, Edwards' or Patau's syndrome. (
  • Amniocentesis is usually carried out between the 15th and 20th weeks of pregnancy but may be later if necessary. (
  • One of the main risks associated with amniocentesis is miscarriage , which is the loss of the pregnancy in the first 23 weeks. (
  • The risk of amniocentesis causing complications is higher if it's carried out before the 15th week of pregnancy, which is why the test is only done after this point. (
  • Amniocentesis is usually done in the second trimester of pregnancy at 15 to 18 weeks. (
  • Done between 15 and 20 weeks of pregnancy, amniocentesis is not recommended unless absolutely necessary since it has been known to cause miscarriage in some cases. (
  • The results of genetic amniocentesis can help you determine whether or not you want to continue with the pregnancy, and if you decide to keep the baby then special prenatal care will have to be arranged. (
  • There were a total of 580 miscarriages from 63,273 amniocentesis procedures with a weighted risk of pregnancy loss of 0.91% (95%CI: 0.73 to 1.09). (

  • During pregnancy, cell samples can be collected from the fetus using amniocentesis or chorionic villi sampling. (
  • Genetic counseling and further testing, such as chromosome analysis before pregnancy, or amniocentesis during pregnancy, may be recommended in adults with atrial septal defects. (
  • This can be accomplished using procedures such as an amniocentesis or chorionic villus sampling (CVS), after which parents can explore their options relating to the pregnancy. (

  • Mosaic tetrasomy 9p at amniocentesis in a pregnancy associated with a favorable fetal outcome, perinatal progressive decrease of the aneuploid cell line and cytogenetic discrepancy in various tissues. (
  • In addition, growing number of complications during pregnancy such as twin-to-twin transfusion, diabetes, and RH incompatibility will continue to impact growth of the global amniocentesis market positively. (
  • Constant rise in obesity during pregnancy has resulted in significant increase in transabdominal thickness hence, needles larger than 150 mm are gaining huge demand for transabdominal amniocentesis fluid collection in such women population due to enhanced safety and requires less needle puncture. (
  • Fetal loss rates following CVS and amniocentesis are often difficult to estimate, as large populations have not been followed from early pregnancy to provide accurate background loss rates of pregnancy. (
  • The total pregnancy loss rate in necessarily higher following CVS than amniocentesis, because CVS is performed at an earlier gestational age, when the risk of spontaneous loss is higher. (
  • A Cochrane review found that the total pregnancy loss rate following TA CVS was equivalent to that of 2nd trimester amniocentesis, whereas TC CVS was associated with a slightly higher risk of miscarriage. (
  • The most recent systematic review demonstrated pregnancy loss rates for CVS vs. amniocentesis to be 0.7% vs. 0.6% within 2 weeks post-procedure, 1.3% vs. 0.9% up to 24 weeks, and 2.0% vs. 1.9% for the entire pregnancy, suggesting similar risks. (

  • Often performed to decide if the fetus is afflicted with a genetic condition such as Down syndrome chromosomal abnormality health care provider recommend for a diagnostic test, amniocentesis. (
  • It's not done as often as other diagnostic tests (such as amniocentesis and chorionic villus sampling ), but may be used if results from those tests are not conclusive. (
  • Other diagnostic methods, such as NAT testing of amniocentesis specimens or serial ultrasounds, may provide additional information to help determine whether the IgM test results suggest a recent infection. (
  • During amniocentesis, a small sample of the fluid that surrounds the fetus is removed. (
