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.
Hello. 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.
