I had it done. Basically you get your blood drawn and they measure the back of the baby`s neck during an ultrasound. They then determine what risk of having a baby with a birth defect or disease. If you test high, they`ll order a 2nd set further into the pregnancy. Mine came out fine, so no futher testing was needed.

Integrated Prenatal Screening (IPS) Integrated Prenatal Screening (IPS) consists of 2 blood tests coupled with a nuchal translucency (NT) ultrasound used to determine fetal risk for Down syndrome, Trisomy 18, and neural tube defects. Detection rate ~90% with a 3% false positive rate. (1) 1st blood test: done between 11-13 weeks and 6 days Biochemical marker used: pregnancy associated plasma protein A (PAPP-A) (2) NT ultrasound: done between 11-13 weeks and 6 days (3) 2nd blood test: done ideallly between 15-16 weeks gestation Biochemical markers used: alpha feto-protein (AFP), unconjugated estriol (uE3), human chorionic gonadotrophin (hCG). Note: If an NT measurement is not available, an IPS risk can be generated using only biochemical markers with the addition of a second trimester marker known as inhibin (DIA). If the 2nd blood draw is not done, then an IPS risk can only be calculated based on the NT measurement and PAPP-A. The detection rate is then lowered.
