DIFFERENT TYPES OF PRENATAL TESTS

There are two types of prenatal tests, screening and diagnostic, and they differ based on the outcome:

  • Screening tests are non-invasive and identify pregnancies at a greater risk for a birth defect or genetic condition, but they are not not conclusive.  If your risk is increased you will probably be offered a prenatal  diagnostic test.
  • Diagnostic tests are mostly invasive tests and confirm the presence or absence of a specific genetic condition.
