  • Prenatal Screening Tests: These tests can tell you if your fetus has aneuploidy or additional conditions similar to it.
  • Prenatal diagnostic tests: These tests can tell you whether your fetus actually has certain disorders. These tests are performed on cells from the fetus or placenta obtained through amniocentesis or chorionic villus sampling (CVS). FAQ 164 Prenatal Genetic Diagnostic Tests focuses on these tests.

Generally speaking, both screening and diagnostic tests are offered to all pregnant women.

First trimester screening includes a pregnant woman’s blood test and an ultrasound test. Both the tests are usually done together and are done between 10 weeks and 13 weeks of pregnancy.

Second-trimester screening involves the following tests: This measures the levels of four different substances in your blood. There is a quad test screening for Down syndrome, trisomy 18 and neural tube defects. It is performed between 15 weeks and 22 weeks of pregnancy. Ultrasound exams performed between 18 weeks and 20 weeks of pregnancy check for major physical defects in the brain and spine, facial features, abdomen, heart, and limbs.

First- and second-trimester test results can be combined in a variety of ways. Combined test results are more accurate than earlier test results. If you choose combined screening, keep in mind that final results are often not available until the second trimester.

A positive screening test result for aneuploidy means that your fetus is at a higher risk of having the disorder than normal. This does not mean that your fetus definitely has the disorder.

Diagnostic testing with CVS or amniocentesis that gives a more definitive result is an option for all pregnant women. Your doctor will help you decide on next steps in this regard.

Any type of test shows you a possibility. Your doctor can suggest next steps depending on the likelihood of the problem.

It is your choice whether to undergo prenatal genetic testing or not. Your personal beliefs and expenses can be important factors in deciding on prenatal testing.

This fact may be important in how you use the results of the prenatal screening test in your pregnancy care. Remember that a positive screening test only tells you that your baby is at high risk of having Down syndrome or other aneuploidy.
