The cost of the NT test is between $100 and $200, which varies from region to region and from hospital to hospital, depending on the local situation.
Generally, after 14 weeks of pregnancy, you can have an NT test, which is the thickness of the transparent layer at the top of the nuchal region of the fetus. If the thickness is thicker, the possibility of fetal malformation cannot be ruled out.
If the results are normal, regular pregnancy tests should be performed. If the results are abnormal, noninvasive DNA testing should be performed to rule out fetal malformations.

Solutions for high NT values:
(1) If the NT measurement is greater than 3mm, the mother-to-be can consult the doctor's opinion to decide whether to do further diagnostic tests such as non-invasive prenatal genetic testing or amniocentesis.
(2) If the thickness has reached 6mm, the risk of fetal abnormalities is high: Down syndrome, other chromosomes, genetic syndromes and heart problems, requiring further amniocentesis or chorionic villus biopsy to clarify the situation.
