  • viral
  • As previously occurred with other largely asymptomatic viral infections posing perinatal transmission risk (such as HIV or cytomegalovirus), we must develop and implement rapid, sensitive, and specific screening and diagnostic testing for both viral detection and estimation of timing of exposure. (nih.gov)
  • Zika
  • Testing for Zika virus infection in pregnancy: key concepts to deal with an emerging epidemic. (nih.gov)
  • Unfortunately, despite an unprecedented surge in attempts to rapidly advance perinatal clinical testing for a previously obscure arbovirus, there are several ongoing hindrances to molecular- and sonographic-based screening and diagnosis of congenital Zika virus infection. (nih.gov)
  • Zika virus RNA can be detected in placental and fetal tissues, which can provide an opportunity to diagnose maternal Zika virus infection and can be considered when maternal serologic testing is not definitive or is negative outside the optimal testing window. (cdc.gov)
  • In the 50 U.S. states and District of Columbia, placental testing provided a confirmed diagnosis of recent maternal Zika virus infection for 10% of live births with possible maternal exposure to Zika virus that lacked definitive evidence of a maternal or congenital Zika virus infection. (cdc.gov)
  • Testing of placental tissues from live births provided definitive evidence of maternal Zika virus infection. (cdc.gov)
  • Although the proportion of live births for which placental tissue was RT-PCR-positive for Zika virus was relatively low, testing of placental tissues from live births can continue to be considered when results of maternal Zika virus testing are not definitive or testing is not performed within the optimal time. (cdc.gov)
  • Ensuring appropriate Zika virus testing and clinical follow-up of infants, according to published CDC guidance is critical in order to identify congenital Zika virus infection. (cdc.gov)
  • In accordance with recent guidance ( 3 , 4 ), CDC provides Zika virus testing of placental and fetal tissues in clinical situations where this information could add diagnostic value. (cdc.gov)
  • Zika remains in the bloodstream for only about a week, while urine testing may detect the virus in a patient between 1 and 20 days of contracting the illness. (aacc.org)
  • The Food and Drug Administration has authorized the use of an experimental test to screen blood donations for contamination with the Zika virus. (aacc.org)
  • Texas Children's Hospital and Houston Methodist Hospital have developed a rapid test for the Zika virus-a milestone in responding to the outbreak. (aacc.org)
  • Using blood, amniotic fluid, urine, or spinal fluid, the test can detect genetic material from the Zika virus and provide results in just a few hours. (aacc.org)
  • Significantly, the test can also distinguish Zika virus infections from other mosquito-borne illnesses, such as dengue, chikungunya, or West Nile. (aacc.org)
  • Laboratory testing for Zika and other arboviruses ( AR thropod- BO rne virus) is available at the CDC and several state health departments. (aacc.org)
  • Antigen
  • Because virus proteins or infectious virus is not produced, culture methods or antigen-based testing is of little use for carrier screening. (cefas.co.uk)
  • specimen collection
  • The specific tests performed will depend on the timing of the specimen collection relative to illness onset and clinical information. (aacc.org)
  • urine
  • New data from the CDC explains why doctors should be testing patients' urine samples every time. (aacc.org)
  • results
  • CDC guidance is available for determining the appropriate testing algorithm and interpreting test results. (aacc.org)
  • Plaque reduction neutralization test results were interpreted using the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) criteria. (ajtmh.org)
  • The test offers the advantages of ease of performance, ease in the calculation of results, lower cost, and increased speed. (ajtmh.org)
  • time
  • Thrombin time (TT) frequently exceeded 200 seconds even at low plasma concentrations of lepirudin, which renders this test unsuitable for routine monitoring of Refludan therapy. (drugs.com)
  • No adverse reactions to the drug were encountered, and cycloguanil pamoate effected dramatic reduction in lost-duty time and hospital costs compared with patients treated with antimonials. (ajtmh.org)
  • blood
  • Additionally, according to the National Institutes of Health, a blood test can be performed to determine the amount of carbon dioxide in a person's blood. (reference.com)
  • cells
  • By 24 hours eosinophils were the prominent cells in the inflammatory reaction, with large numbers replacing neutrophils in penetration tracks. (ajtmh.org)
  • plasma
  • This was observed with increasing plasma concentrations of lepirudin, with no saturable effect up to the highest tested dose (0.5 mg/kg body weight intravenous bolus). (drugs.com)
  • found
  • 9 In a study 10 performed in New York, no spores were found in any of the 236 products that were tested. (aafp.org)
  • According to microbiologic testing, up to 25 percent of honey products have been found to contain spores. (aafp.org)
