Current NYS screening algorithm for CAH.
*A repeat is requested when a specimen collected on day of birth (DOB) is received but the specimen is nevertheless tested. For DOB specimens: ≥ 1751 g infants are referred if the 17-OHP value is ≥ 110 ng/ml; 1001–1750 g infants are referred if the 17-OHP value is ≥ 117 ng/ml; ≤ 1000 g infants are referred if the 17-OHP value is ≥ 149 ng/ml. In addition, for specimens collected 14–40 days after birth: ≤ 1750 g babies are referred if the 17-OHP value is > 55 ng/ml and ≥ 1751 g babies are referred if the 17-OHP value is ≥ 35 ng/ml. For specimens collected > 40 days after birth, babies are referred if the 17-OHP value is ≥ 35 ng/ml. **Emergency level 17-OHP values are referred immediately and prior to repeat confirmatory screening. 17-OHP, 17-hydroxyprogesterone.
