Many expectant mothers undergo a test during pregnancy – the NT test. So, what is the normal range of NT values? Today we will learn more about it. NT examination uses B-ultrasound to measure the thickness of the nuchal translucency of the fetus to assess whether the fetus has the risk of chromosomal abnormalities and structural malformations. Generally speaking, the normal range of NT values is below 2.5mm. If the NT value is greater than or equal to 2.5mm, it requires attention. This may indicate that the fetus has an increased risk of chromosomal abnormalities or structural malformations, which requires further examination, such as amniocentesis or chorionic villus biopsy. However, it should be noted that the NT value is only a screening indicator and cannot diagnose whether there is a problem in the fetus. Therefore, if the NT value is abnormal, don’t be too nervous or worried. You need to make a comprehensive judgment based on other examination results and the doctor’s advice. In addition, the timing of the NT examination is also important. It is generally recommended to do it between 11 weeks and 13 weeks + 6 days of pregnancy. The NT value measured during this time period is the most accurate. Finally, I would like to quote a famous saying: \”Every child is a gift from God to us.\” Whether normal or abnormal, we should cherish and love them. I hope every expectant mother can go through pregnancy smoothly and give birth to a healthy and lovely baby. The above is a professional article about \”What is the normal range of NT value\”, using colloquial expressions, I hope it will be helpful to you.
