FIRST TRIMESTER ULTRA-SCREEN/INSTANT RISK ASSESSMENT (IRA)

First-Trimester screening is a normal, reliable test used for early pregnancy evaluation.  It consists of two parts:

1. ) A blood test, drawn from either your arm or your finger.
2. ) A detailed ultrasound examination of your baby.

The IRA program allows the earliest possible risk assessment for Down syndrome (Trisomy 21), Trisomy 18, and Trisomy 13.

By having your blood drawn at 10 weeks gestation, you will be able to get immediate results on the day of your ultrasound examination, which is carried out between 11.5 & 12.5 weeks gestation.

One of the specialist physicians at Atlanta Perinatal Consultants will conduct and interpret your ultrasound examination and combine those results with those of your earlier blood test.  This will provide us with a final calculation of your risk for Down syndrome, Trisomy 18 and Trisomy 13. In the event of an “at risk” result, we will provide you with additional consultation, genetic counseling and testing options as appropriate to your needs.
