Patient's question:
I am 12 weeks pregnant. This morning, my husband accompanied me to the hospital for the Down syndrome screening. The detailed test report indicated a 1:899 risk for trisomy 21 in the Down syndrome screening. I want to know if a 1:899 risk for trisomy 21 is normal. The doctor recommended an NIPT (Non-Invasive Prenatal Testing). Is it necessary?Doctor's answer:
The result of the 21-trisomy screening in this detailed check shows a critical risk value. The normal value is 1:270. If it is higher than this number, it indicates low risk. If it is between this value and 1:1000, it indicates a critical risk value. In fact, this situation can also be considered low risk, and there should be no problems at all. However, if you and your family are very concerned, you can also consider undergoing further detailed testing.
