Hi,

I just got the result of my first trimester test which combined a blood test and NT scan.
In the result, there are the following risk factors, and I'm wondering which one really tells the risk I'm having? Could any one that knows please tell me? Thanks a lot.

background risk of TRisomy 21 1:883
Adujsted risk of Trisomy 21 1: 16395
background risk of TRisomy 13+18 1:1744
Adujsted risk of Trisomy 1:34855
