The first three months of pregnancy are a dangerous stage for pregnant women to miscarry, so they need to be careful and pay attention to safety at all times. After the third month of pregnancy, that is, from 11 to 13 weeks, you can go to the hospital for an NT examination. Early abnormality checkup. This examination can help pregnant women and their families understand the condition and development of the fetus in the pregnant woman's belly, and initially determine whether the fetus may be malformed. Is the tenth week of pregnancy generally stable?

What is the NT test in the third month of pregnancy?

The NT test uses ultrasonic scanning to check for small abnormalities in the first trimester. NT refers to the nuchal translucency of the fetus. This imaging examination is used to check the thickness of the fluid accumulation in the subcutaneous tissue fluid behind the fetal neck. Infant chromosomal diseases and fetal abnormalities, such as hydrocephalus, fetal spina bifida, and cardiac malformations, can be diagnosed early. The time for NT inspection is very strict. The best time for examination is between 11 and 14 weeks of pregnancy.

Simply put, the thicker the thickness, the greater the probability of fetal abnormalities. It is worth reminding that NT examination is the first time to detect malformations and can detect the risk of malformations. A high risk does not necessarily mean that you will have malformations. Of course, normal NT values ??do not mean that the fetus has no abnormalities. NT examination only indicates the risk of fetal abnormalities. If the thickness of the NT examination exceeds the normal value, it is necessary to conduct next-level abnormality examination, such as related chromosome examination, and pay close attention to the examination results and actively cooperate with the examination. Then, when abnormal fetal development is detected, you should stay calm and consult a doctor: understand the causes and results of the abnormality, and conduct a reexamination to eliminate misdiagnosis. If the reexamination result is good, then you should be happy and pay attention to the prenatal examination. If the examination results confirm that the fetus does exist If the deformity occurs, please follow the doctor’s instructions for treatment.

Prenatal examination items in early pregnancy generally include gynecological speculum examination, leucorrhea examination, cervical scraping examination, gynecological triadic examination, ultrasound examination, etc.

Other inspection aspects are based on your own circumstances. If you suffer from heart, liver, kidney, thyroid and other diseases, you need to consult a physician to understand whether continuing the pregnancy will increase the risk. When is the best time to do NT examination?

When should pregnant mothers start to do NT examination? NT is the abbreviation of nuchal translucency, which refers to the "nuchal translucency", which is the level of the fetal cervical vertebrae from the facial skin to The maximum thickness between subcutaneous soft tissues. NT examination is the measurement of this indicator.

NT examination is best done between 11 and 14 weeks of pregnancy. Examination beyond 14 weeks will be inaccurate and earlier than Down syndrome. NT examination is mainly measured through B-ultrasound. If the final measurement value is less than 3 mm, it is normal. If it exceeds 3 mm, further examination, such as amniocentesis, etc., should be considered.

According to relevant statistics, the detection rate of Down syndrome can reach more than 85% through NT examination and then combined with blood tests. In addition to pregnant women who have decided to undergo amniocentesis, it is best for pregnant mothers to do maternal blood screening for Down syndrome and fetal nuchal translucency examination to ensure that they give birth to a healthy baby.

The purpose of nuchal translucency examination is to diagnose chromosomal diseases and fetal abnormalities caused by various causes at an early stage of pregnancy.

Because research has found that between 11 and 14 weeks of pregnancy, if the fetus has Down syndrome or the heart does not develop well, the nuchal translucency will thicken. Thickening of the nuchal translucency is related to fetal karyotype, fetal congenital heart disease and other structural malformations. The thicker the nuchal translucency, the greater the probability of fetal abnormalities.

Transvaginal ultrasound examination is performed on pregnant women between 11 and 14 weeks of pregnancy to measure the thickness of the fetal neck pellucida
