Question
Hello doctor,
I am 15 weeks pregnant and had an ultrasound with a nuchal translucency of 1.2mm at 12 weeks 5 days. So the doctor let me ask if the nuchal translucency measured at more than 12 weeks pregnant is 1.2mm, is it okay? I forgot to ask the doctor what the results of Trisomi 21 and Trisomi 18 are? Please advise, thank you doctor.

Hello,
With the question "Neck nuchal translucency measured at more than 12 weeks gestation is 1.2mm, is it okay? ", the doctor would like to answer as follows:
Nuchal translucency, also known as the light on the back of the neck, is the accumulation of fluid under the skin in the nape of the fetus. All fetuses between 11 weeks and 14 weeks of gestation have this fluid at the nape of the neck. Measuring nuchal translucency to check the nape of the baby's neck by fetal ultrasound helps doctors diagnose the risk of Down syndrome at the earliest, which can be the basis for advising whether the mother needs further testing. NIPT prenatal screening test or some other test.
Nuchal translucency measured at 12 weeks 5 days 1.2mm is within normal limits; However at that time you should combine it with another screening test: Double test or more advanced NIPT , which will tell you if you are in the risk group for disorders of chromosome 13,18,2, ...are not. If you have already done the Double test, now you have the results sheet, if you still do not understand the results you should go back to your obstetrician, who will explain it to you.
