Is the NT value of 2.3mm dangerous?

Generally, expectant mothers need to have their NT value checked around 10-15 weeks of pregnancy to judge the health of the fetus. If the test value is higher than the standard value, it indicates that the fetus may be deformed and further examination is required. So, how much is the normal range of NT value?

Is there any risk with a nt value of 2.3mm?

The Nt test uses ultrasound to accurately measure the thickness of the fetal nuchal translucency to determine the risk of fetal chromosomal diseases and can also detect some fetal structural abnormalities.

Nt test 2.3mm belongs to the normal range, the standard value is below 2.5mm, and more than 2.5mm is considered thickening. The nt test is mainly performed between 11 weeks and 13 weeks + 6 days of pregnancy. It is also an early test to rule out fetal hypoplasia. All pregnant women who meet the conditions can undergo an nt test. Not all pregnant women need to do it, but older pregnant women, pregnant women with twins, pregnant women with a bad maternal history, and pregnant women at high risk of Down syndrome must do the NT test.

The NT value (neck translucency) refers to the thickness of the fluid accumulation in the subcutaneous tissue fluid behind the fetus's neck. When the neck translucency is greater than or equal to 2.5mm, it can be identified as thickening of the neck translucency. The degree of thickening of the neck translucency is closely related to fetal abnormalities. The more obvious the thickening of the nuchal translucency, the higher the chance of fetal abnormality and the more serious the degree of abnormality.

If repeated accurate measurements are higher than the standard value, then it is recommended that the expectant mother undergo amniocentesis to check the sex chromosomes. Check the Down's test to see if there are any abnormalities. To eliminate deformed fetuses. Most of the thickened NT will naturally disappear by 20 weeks of pregnancy. Generally, the NT value test is performed 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.

The NT value is an ultrasound measurement of the thickness of the nuchal translucency layer of the fetus at 10-14 weeks of pregnancy. Any value <2.5mm is considered normal, and any value greater than or equal to 2.5mm is diagnosed as thickening of the nuchal translucency layer. When the cyst thickens extremely, it may cause cystic hygroma in the fetal neck, which is a congenital disease.
