Pregnancies2
In white Caucasian populations about 10% of all pregnancies involve a mother with rhesus (Rh) D negative blood group and an RhD positive fetus, potentially placing the mother at risk of sensitisation and future babies at risk of haemolytic disease of the fetus and newborn. (biomedcentral.com)
Fetal RHD genotyping of this material has the potential to enable antenatal prophylaxis targeted at the 60% of pregnancies with an RhD positive fetus, thereby saving anti-D costs. (biomedcentral.com)

The use of fetal scalp blood testing originated in Germany in 1961 and required 0.25 mL of blood drawn from the fetus. (wikipedia.org)
An amnioscope with a light source is used to expose the scalp of the fetus, and the procedure requires at least 3 to 4 cm of cervical dilation to visualize the fetal scalp. (wikipedia.org)
Baby's2
This response is indicative that the baby is healthy and receiving enough oxygen and this test also provides a safe alternative as opposed to taking a small blood sample from the baby's scalp and testing the acid-base levels in the blood. (wikipedia.org)
Prophylaxis following delivery was introduced in the 1960s, with a blood cord serology test used to identify the baby's RhD status. (biomedcentral.com)
Death1
Potential risks include bleeding from the fetal blood sampling site, infection, changes to heart rate, and death. (wikipedia.org)
Prevent1
Anti-D prophylaxis (anti-D IgG) can be given to prevent a woman producing antibodies against fetal RhD-positive blood cells and becoming sensitised. (biomedcentral.com)
Presence1
SARS-CoV-2 presence was detected in the initial- and subsequent-trimester fetal brain associated with hemorrhage in the cortex. (news-medical.net)
Test2
Fetal scalp stimulation is a second-line test that helps provide specialists reassurance that the labor process can safely continue. (wikipedia.org)
The Foetal Blood Serum Infusions reagent is RUO (Research Use Only) to test human serum or cell culture lab samples. (cd1234567890.com)
Potential1
Fetal scalp blood testing should be avoided when there is a potential risk of infection (e.g. (wikipedia.org)
Research3
Description: The Morphine ELISA kit for serum or whole blood is intended for use in research laboratories. (cd1234567890.com)
In 2011, I started my own laboratory at WEHI with a consistently innovative research program focused on the biology of blood production and function. (edu.au)
In brief, my research team uses cutting edge imaging, clonal tracking (cellular barcoding), genomics technologies, and functional assays (in vivo and in vitro) to tackle long-standing questions about the biology of blood production. (edu.au)
Scalp14
Fetal scalp blood testing is a technique used in obstetrics during active labor to confirm whether a fetus is receiving enough oxygen. (wikipedia.org)
This correlation can only be concluded by sampling fetal scalp blood and measuring acid status. (wikipedia.org)
Therefore, fetal scalp blood testing could be used to reduce the number of unnecessary emergency caesarean sections made on the decision of fetal heart rate alone. (wikipedia.org)
Therefore, due to limitation in adding value, fetal scalp testing can serve as second line test to provide and strengthen the information on fetal acidosis and hypoxia status obtained from cardiocotography (CTG). (wikipedia.org)
The use of fetal scalp blood testing originated in Germany in 1961 and required 0.25 mL of blood drawn from the fetus. (wikipedia.org)
Now, fetal scalp blood testing requires a considerable less amount of blood depending if testing pH or lactate. (wikipedia.org)
One safer alternative to fetal scalp blood testing is what is called fetal scalp stimulation. (wikipedia.org)
Fetal scalp stimulation is a second-line test that helps provide specialists reassurance that the labor process can safely continue. (wikipedia.org)
This response is indicative that the baby is healthy and receiving enough oxygen and this test also provides a safe alternative as opposed to taking a small blood sample from the baby's scalp and testing the acid-base levels in the blood. (wikipedia.org)
During a fetal scalp blood testing procedure, a small incision on the fetal scalp is made and blood is collected using a capillary tube. (wikipedia.org)
An amnioscope with a light source is used to expose the scalp of the fetus, and the procedure requires at least 3 to 4 cm of cervical dilation to visualize the fetal scalp. (wikipedia.org)
Fetal scalp blood testing is associated with a relatively high failure rate of up to 20% due to variables such as sample contamination with air or amniotic fluid, or inadequate sample volume. (wikipedia.org)
Fetal scalp blood testing should be avoided when there is a potential risk of infection (e.g. (wikipedia.org)
A vaginal examination (VE) was carried out and a fetal scalp electrode was attached. (hdc.org.nz)

13. At 9.40pm, the fetal blood sample showed severe acidosis and Dr B decided to proceed with a Caesarean section. (hdc.org.nz)
Heart rate3
While continuous fetal heart rate monitoring is the primary method for assessing fetal wellbeing during labor, a change in fetal heart rate is not indicative of fetal acidemia. (wikipedia.org)

8. At 9pm, further decelerations were noted and the fetal heart rate was slow to recover. (hdc.org.nz)
Sample3
With the help of continuous ultrasound guidance to place the needle in the abdomen into the tiny fetal blood vessel, the blood sample gets obtained and sent for testing. (wikipedia.org)
After blood collection, pH and/or lactate levels are tested requiring up to 25 minutes per sample. (wikipedia.org)
