Serum Genetic Screening is a blood test that can help identify babies that may have certain birth defects. Conditions that the Serum Screening can help detect include Downs Syndrome, Trisomy 18, spina bifida, anencephaly, ventral wall defects and Smith-Lemli-Opitz syndrome. There are three different screening tests (Full Integrated, Serum Integrated, and Quad Test) that use blood samples with or without a first trimester ultrasound to predict whether the chance of a birth defect is average, above average, or below average. If the results suggest an increased risk of a certain birth defect, you will be given options for further testing. These options may include another blood test, an ultrasound examination or possibly an amniocentesis to give you accurate information regarding the health of your baby. Fortunately, most babies are normal and the Serum Screening indicates average or below average risk for a problem. If the result is an above average risk, however, remember that most babies are still normal.

Please refer to the handouts given to you at your initial visit for more information about these tests.

It is important to keep in mind that the Serum Screening is only a tool to help decide who should be offered further testing. The tests do occasionally indicate an increased risk of birth defects in pregnancies that have normal babies.
