Patient's question:
What does nt2.0mm mean? The doctor said it's necessary to undergo a non-invasive test. What disease is being carefully examined? I had high-risk behavior for a year and a half before becoming pregnant, and then I had the child. Could the child have HIV? Is it necessary to have a thorough examination?Doctor's answer:
NT represents the translucent layer of the fetus's neck, and under normal circumstances, a thickness of 2.0 mm is still within the normal range. It is primarily used to screen for the exclusion of trisomy 21 syndrome, also known as Down syndrome. The general guideline is that if the thickness is less than 2.5 mm to 3 mm, an invasive DNA test should be performed. However, the criteria may vary between different regions and hospitals. You should follow the advice of your attending physician during your face-to-face consultation.
