When can NT examination be done? When is the most accurate time for NT examination?

Everyone must have heard of NT examination, but do you know how to do it? Today, let's follow the editor to learn about when NT examination can be done and when it is most accurate.

When can NT test be done?

When should pregnant mothers start to do NT examination? NT is the abbreviation of nuchal translucency, which refers to the "nuchal translucency", that is, the maximum thickness between the skin and the subcutaneous soft tissue at the horizontal sagittal plane of the fetal cervical spine. The NT examination is to measure this indicator. The NT examination is best done between 11 and 14 weeks of pregnancy. The examination will be inaccurate after 14 weeks, which is earlier than the time of Down syndrome. The NT examination is mainly measured by B-ultrasound. The final measurement value is less than 3 mm, which is normal. If it exceeds 3 mm, further examination should be considered, such as amniocentesis.

When is the most accurate time to do NT test?

Because the fetus is too small to observe the nuchal translucency before 11 weeks of pregnancy, and the fetus gradually develops after 14 weeks of pregnancy, it may absorb excess fluid from the nuchal translucency and affect the test results. Therefore, it is best for pregnant women to do NT within 11-14 weeks of pregnancy to avoid inaccurate test results.

What should I pay attention to when doing NT examination?

Pregnant women need to do various physical examinations after pregnancy. For the sake of the fetus, they must do NT examination. NT examination is a B-ultrasound examination item. It does not require blood tests. Eating and drinking will not affect the test results. Therefore, there is no need to fast before the examination. Because the fetus is too small to observe the nuchal translucency before 11 weeks of pregnancy, and after 14 weeks of pregnancy, the fetus gradually develops and may absorb excess body fluids from the nuchal translucency, affecting the test results. Therefore, it is best for pregnant women to do NT within 11-14 weeks of pregnancy to avoid inaccurate test results. It is best to make an appointment for NT in advance. Generally, you can start to make an appointment with the hospital before 11 weeks of pregnancy for scheduling. Do not make an appointment after 13 weeks of pregnancy to avoid waiting in line for too long. Doing NT after the gestational age will affect the accuracy of the test results.

How much does NT test cost?

In fact, the price may vary from place to place, generally between 100 yuan and 400 yuan. There are two main factors that affect the cost of NT examination:

1. Choose a hospital:

Generally speaking, choosing a large hospital, because it has advanced medical equipment and experienced obstetric directors, the price of normal delivery is relatively higher than that of general outpatient clinics and small hospitals, but it will be safer. Therefore, obstetric experts recommend that mothers must choose a regular large comprehensive hospital for NT examination.

2. Whether it belongs to the medical insurance unit:

Some hospitals are designated medical insurance institutions. If mothers who have NT examinations have maternity insurance, they can be reimbursed, but the reimbursement amount varies from hospital to hospital. However, it is worth noting that relevant prenatal examinations must be conducted within the scope of maternity insurance, otherwise they will not be reimbursed.
