Which tests do I need?

  • The first trimester extended screening test, which consists of a blood test and an ultrasound exam, is recommended for every expectant mother. If this examination shows that the risk is low, then we recommend that the next tests be the 20th week, followed by the 30th week screening tests. If the risk is high, then further tests are necessary.
  • If the results of the first trimester extended screening test show a high risk (> 1/150), PrenaTest™ is recommended as an alternative to chorionic villus sampling, which carries a 1% risk of miscarriage. PrenaTest is done from the mother’s blood, which makes is completely safe for the pregnancy. PrenaTest™ is also recommended if any other risk estimate (e.g. maternal age, quad screen etc.)shows a high risk and the expectant mother has not undergone more high-efficiency traditional screening tests (e.g. combined-extended screening) for a more precise risk assessment. Of course, parents can request the test without any medical reason, but only following the ultrasound exam, because PrenaTest does not replace the ultrasound exam, as several disorders and problems that cannot be detected with this test can be detected using ultrasound.
  • After a positive PrenaTest™ result, at the request of a high-risk expectant mother, or with other genetic  indications, an invasive test (chorionic villus sampling or amniocentesis) is recommended.
