Hello doctor,

I am a 44-year-old female. After my three miscarriages, I am 13 weeks pregnant now with IVF treatment. I have got my NT scan with double marker blood test.

The results are as follows: Biochemical Trisomy 22 risk: 1:249, combined Trisomy 21 risk. Using NT & Other parameters: 1:946. Trisomy 18 risk using NT: 1:10000. PAPP-A: 4.97 mIU/mL and Fb- HCG: 30.9 ng/mL. Crown Rump length: 70.3 mm, Nuchal Translucency MoM : 0.99, Nasal Bone: Present, Nuchal Translucency: 1.74 mm

Is my report fine? I am really worried.



Welcome to icliniq.com.

The NT (nuchal translucency) scan levels of nuchal translucency are normal with NT < 2.5 mm.

However biochemical trisomy 21 risk is high but the combined NT+ biochemical risk is low at 1:946.

You may upload the picture of the cutoff graph for a convincing opinion regarding whether you would need amniocentesis for karyotyping confirmation or not.

Thank you doctor,

This is the graph I have got in my report. I have attached it herewith. Please advise.



Welcome back to icliniq.com.

I have seen the graph (attachment removed to protect patient identity) and the bar is well below the cutoff line.

Hence there is minimal or no risk for the child to be triatomic.

There is no requirement of amniocentesis for karyotyping.

However, a quadruple test may be repeated at 15 weeks of gestation as protocol.
