Regarding NT scan and dual Marker Test
Hi. I'm 29 years old. We had a NT scan done last week at 13th week of pregnancy and the result was 2.4. We got dual marker test reports and risk for Down syndrome is 1.253 . Is it a matter of concern? What are the chances of the baby being born normal?

Positive NT SCAN depends on the 95th centile value for that specific gestation/CRL .
SINCE YR NT is 2.4 ,it's normal.
Dual markers interpretation
More than 1:1000- low risk--> only do anomaly TIFFA SCAN at 18-20 weeks
1:251- 1:1000- INTERMEDIATE RISK --> do NIPT/CELL FREE DNA TEST or u can wait for scan at 16wks
<1:250- POSITIVE TEST--> do confirmatory test ( amniocentesis)
Next Steps
