Do you hold your urine during NT examination?

The NT examination is a surgical procedure for screening fetal anomalies. This surgical procedure needs to be performed at 12 weeks of pregnancy. It mainly examines the thickest skin on the fetus's neck. There is no need to hold urine or have a blood test. Holding urine is only required for B-ultrasound or urine tests. Pregnant women should understand the precautions before the NT examination, and remember that they must undergo a NT examination during pregnancy to avoid the birth rate of deformed babies.

Do I need to hold my urine for a pregnancy test?

1. NT examination is usually performed within 10-13 weeks + 6 days. There is only one item to measure whether the thickness of the nuchal translucency layer is within the normal range. If there is any abnormality, corresponding line screening is required. You do not need to hold your urine for this test.

2. Conventional obstetric B-ultrasound examinations mainly focus on the development and gross structure of the fetus. With the development and popularization of transvaginal ultrasound, more in-depth attention is paid to the proportional relationship between the various tissue structures of the fetus.

3. Quantitative analysis of detection indicators is used to predict whether the fetus has certain defects, especially chromosomal abnormalities, such as fetal nuchal translucency measurement, which is becoming one of the effective methods for prenatal screening of fetal chromosomal abnormalities.

What is nt

1. The nuchal translucency is referred to as NT, which refers to the thickness of fluid accumulation in the subcutaneous tissue at the back of the fetal neck. Clinical studies in the past decade have found that using ultrasound to measure the thickness of the nuchal translucency has very important clinical significance. As the thickness increases, the possibility of fetal abnormalities also increases.

2. Among fetuses with thickened nuchal translucency, a considerable number of them are confirmed to have chromosomal abnormalities, anatomical abnormalities or some genetic syndromes. It has been reported that among fetuses with thickened nuchal translucency at 10-14 weeks of gestation, about 10% have chromosomal abnormalities.

3. Among fetuses with normal chromosomes and thickened lamina lucidum, about 4-20% have anatomical abnormalities and certain genetic syndromes, especially severe heart defects. Others experienced unexplained intrauterine fetal death and neonatal death (2%).

In fact, pregnant women should not worry about the NT examination. This is just a basic screening for congenital defects such as deformities or mental retardation in the baby. Therefore, you must cooperate with the doctor's examination, and this examination does not require holding urine or fasting. As long as the pregnant mother takes good care of her body and maintains a good mood, it will be fine.
