During pregnancy, it is important to undergo various examinations to ensure the normal development of the fetus, constantly monitor any potential abnormal symptoms, and promptly detect and respond to them. Some parents are also concerned that their babies may have genetic diseases at birth, so they want to undergo a Tang screening test. Can I undergo Tang screening at 14 weeks of pregnancy?
At 14 weeks of pregnancy, a Down syndrome screening test can be performed, usually between 14 and 20 weeks of pregnancy. However, if you want to ensure the accuracy of the test, you can choose between 16 or 18 weeks. These tests test the pregnant woman's red blood cells to determine whether there is a genetic disease. Some fetuses have positive symptoms of Down syndrome, which can often be detected in a timely manner using these testing methods.
If there are abnormal physical manifestations during pregnancy and it is suspected to be a genetic disease of the baby, amniocentesis and chorionic villi examination can be used. These methods can not only understand the development and health of the fetus, but also grasp the degree of genetic lesions in the fetus. If there is really a disease, it can be diagnosed and treated immediately.
In fact, all the examination items at 14 weeks of pregnancy have good results, but before the examination, it is necessary to understand various matters, such as whether fasting is necessary or choosing an appropriate examination time. Some Down syndrome screening tests are not closely related to blood sugar, so it is not necessary to maintain an empty stomach, only to cooperate with the doctor's examination procedures.
