Hi doctor,

I am 12 weeks 5 days pregnant. My NT scan measures 1.6 mm, the double marker PAPP-A is 2.82, and free beta hCG is 36.7 Could you please help with the report? Was it normal? My trisomy 21 is 1:250.

Hello,

Welcome to icliniq.com.

1 in 250 is a high risk for trisomy which means your risk of having a baby with trisomy 21 is 1 out of 250. But this test is only a screening test which means that they just calculate the risk of having a baby with down syndrome. If someone is found at higher risk like yours, then she is offered a diagnostic test (amniocentesis or chorionic villus sampling).

In those tests, a sample of fluid is taken from your baby and examined in labs to confirm the diagnosis accurately.
