Dual marker tests show Down syndrome risk. Should I worry?

Question

Hello doctor,

In my first month of pregnancy, I had a thyroid that increased to 19.1, but I got it under control in 10 to 15 days. My dual marker test came positive for Down syndrome, which is 1:211. I am worried.

Please explain.

Hi,

Welcome to icliniq.com.

As I can see on your report (attachment removed to protect the patient's identity), your gynecologist has also explained that further confirmatory tests would be required for diagnosing Down syndrome.

This test is not accurate, but it definitely flags pregnancies. Hence, an amniocentesis or chorionic villus sampling might be needed if the marker test comes positive. The marker test is a screening test and has its limitations. But this would allow you to discuss with your husband and family how you want to proceed with the pregnancy. Would you want to take the chance, or would you like to terminate it?

After discussing with your family, share and discuss your doubts and concerns with your gynecologist, then proceed further.

I hope this helps.

Please feel free to reach out in case of further queries.

Thank you.
