What is the normal value of nt in prenatal examination?

I believe that many pregnant women cannot understand the results of prenatal examinations. Everyone needs to consult a doctor to know whether the results of the prenatal examination are normal, especially what the NT value is, which many pregnant women may not know. The Nt value is the result of ultrasonic examination, which mainly measures the thickness of the fetal neck transparency. A value less than 2.5mm is normal. If it exceeds this limit, it will affect the normal development of the fetus.

What is the normal nt value during pregnancy

1. The NT value is the thickness of the fetal nuchal translucency measured by ultrasound at 10-14 weeks of gestation. Any value <2.5mm is considered normal, and any value greater than or equal to 2.5mm is diagnosed as thickened nuchal translucency.

2. The nuchal translucency usually grows with the growth of the fetus and gradually disappears after 14 weeks of pregnancy. In China, doctors consider a nuchal translucency greater than 3 mm to be abnormal. Due to different individual conditions, some normal fetuses have more body fluids, which can easily affect the measurement results. If the nuchal translucency is thick, it does not necessarily mean that there is a problem with the fetus.

What should I do if the NT value is higher than normal?

1. If repeated measurements are higher than normal values, it is recommended that the pregnant mother undergo amniocentesis to check chromosomes. Check the Down syndrome test to see if there are any abnormalities. To rule out fetal malformations.

2. Most of the thickened NT will disappear naturally at 20 weeks of pregnancy. Generally, the NT value is checked between 11 and 13 weeks of pregnancy. Generally speaking, ultrasound examination is more accurate. If the NT value is >0.3cm, amniocentesis is required to further rule out fetal malformations.

A normal NT value can better reflect certain aspects of the fetus' health. Abnormalities do not mean that there is a problem with the baby, and repeated checks are needed to ensure whether the data is biased. If a problem is found, the doctor will give sufficient advice. Pregnant mothers do not need to worry too much and should follow the doctor's advice. The doctor will provide appropriate treatment.
