After pregnancy, women must pay attention to various prenatal examinations, which can detect fetal abnormalities and take remedial measures as early as possible. Tang screening is a necessary examination for pregnant women, but many people still have very little understanding of Tang screening. So, what tests should be done for early pregnancy screening?
Women undergo Down syndrome screening in early pregnancy to check for Down syndrome, which is one of the necessary tests during pregnancy. The probability of a child suffering from Down syndrome can be determined through Down syndrome screening, and the examination method is very simple, as long as the pregnant woman undergoes blood tests. If the test shows a high risk of fetal disease, another sheep puncture or chorionic villus examination should be performed.
If the pregnant woman is older, the likelihood of the fetus developing Down syndrome increases, but this does not necessarily mean that older pregnant women will have Down syndrome. If the pregnant woman is older, she can skip the Down syndrome screening and directly undergo amniocentesis to obtain accurate results, and can also choose to undergo non-invasive DNA testing.
Pregnant women should choose the best time to undergo Down syndrome screening, and 15-20 weeks of pregnancy is very suitable for Down syndrome screening. If Tang sieve is done too early or too late, it can easily affect the results of the examination. Everyone should note that Tang screening cannot directly confirm whether the fetus is sick, but can only display the probability of the fetus being sick.
