Hi. My wife is 12 weeks pregnant and everything is normal in her blood report including thyroid, sugar and hemoglobin. The doctor has asked her to go for an NT scan along with Double Marker, which is optional. They said Double Marker will cost 4000 Rs. I need your suggestions. Is Double Marker really required if everything is normal in her blood report?

Double Marker is a screening test for chromosomal anomalies. Even if routine labs are fine, it is still advised. NT scan + Double Marker gives better risk assessment.

I recently did my routine first trimester antenatal blood tests, and my report shows a high risk result for trisomy 21 (1:7) and trisomy 13/18 (1:11). I am 27 years old. I am very worried after seeing this report. Could you please guide me on what steps I should take next to confirm or reduce this risk?
