Patient's question:
I am 8 weeks pregnant and have been following my doctor's advice to regularly undergo prenatal check-ups. Now I realize there are really a lot of tests to be done during pregnancy, such as blood tests and urine tests. The doctor said that in a few weeks, I will need to have an NT scan. I've heard that this test is similar to an ultrasound, but I don't know what its purpose is or what aspect it checks.I would like to know: What is an NT scan?
Doctor's answer:
NT is a test for the translucency of the fetal neck. If the result is high, there is a risk of fetal developmental abnormalities. Under normal circumstances, this value should not exceed 3.0 mm. Exceeding this value indicates a risk of fetal developmental abnormalities. You can wait for the triple screen test during the 15-18 weeks or undergo non-invasive prenatal genetic testing after 12 weeks to assess development.If the biopsy or amniocentesis is not problematic or shows negative results, there is generally no issue. Non-invasive testing is performed for chromosomes 13, 18, and 21.
Prevent various infections (such as colds, diarrhea, etc.). Avoid sexual activity, especially during the first three months. Do not undergo transvaginal ultrasound to prevent cervical stimulation, which could lead to contractions and induce miscarriage.
Attend prenatal checkups regularly. Maintain a positive mood. Engage in moderate exercise.
Generally, the TORCH test can be done around the second and a half month of pregnancy. The triple screen test can be performed after 15 weeks of pregnancy, and the glucose screening test can be done between 24-28 weeks of pregnancy.
