How much does a pregnant woman's NT test cost?

NT examination is one of the prenatal examination items, also known as "the first fetal malformation screening ultrasound". The NT examination is mainly performed on pregnant women between 11 and 14 weeks of pregnancy to accurately measure the thickness of the fetus's nuchal translucency. So, how much does a NT test for pregnant women cost?

The charges for NT examination vary in different hospitals in different regions. Some hospitals require this item to be a self-paid examination item, and some hospitals can go through the maternity insurance procedure. Generally speaking, the price of an NT is around 100-300 yuan. Pregnant women can consult the local hospital for details. So, how to do NT inspection in practice?

1. During the color Doppler ultrasound examination, the fetus's brachiocephalic diameter (CRL) and biparietal diameter are first measured to determine the ultrasound gestational age. Then the fetal structure is checked in sequence, and some important indicators are observed, such as fetal heartbeat, fetal movement, the connection position of the umbilical cord and the fetus, the growth and development of the fetal limbs, the choroid plexus in the brain, etc., as well as fetal abnormalities such as holoprosencephaly, choroid plexus cyst, umbilical hernia, and other growth and development abnormalities.

2. The thickness of the nuchal translucency is measured in the short-axis sagittal cross-section of the fetus, and the fetal head and spine are in a straight line during the measurement. Adjust the magnification so that the fetus' body occupies about 3/4 of the screen size. The measuring points were placed at the inner edges of two high-echo lines for measurement. The two high-echo lines represent the skin echo and the spinal surface soft tissue echo, respectively. The middle part is the nuchal translucency.

3. Take a short-axis sagittal cross-section of the fetus, with the embryo in a naturally flexed position, and accurately measure the thickest position of the echo-free transparent layer of the subcutaneous tissue in the fetus's neck, from the inner edge of the skin layer to the edge of the subcutaneous tissue. Measure accurately three times and take the thickest value.

4. If the thickness of the fetal nuchal translucency is measured to be ≥3mm (or ≥2.5mm and the gestational age calculated based on the fetal head arm diameter is <12 weeks), the pregnant woman is recommended to undergo amniocentesis or chorionic villus sampling for fetal chromosome karyotype analysis.
