Women need to regularly go to the hospital for various examinations during pregnancy, with the purpose of ensuring the physical health of both the mother and the fetus. During different stages of pregnancy, women need to undergo different examinations. When a woman is five months pregnant, non-invasive DNA testing is required. So, what should be noted when conducting non-invasive examinations?
When conducting non-invasive examinations, women need to have blood drawn, but do not need to undergo fasting tests. Many people think that blood drawing should be done on an empty stomach when they hear about it. But non-invasive DNA testing is quite special, and there is no need to be on an empty stomach during blood tests, as long as you do not eat spicy food. Secondly, when women undergo non-invasive examinations, they must remember their examination time.
The best time for non-invasive examination is between 14-18 weeks of pregnancy for women. If the inspection time is missed, it may affect the inspection results and hinder the smooth progress of subsequent inspections. However, checking too early may result in inaccurate information and waste of medical equipment. So women should remember their non-invasive examination time, not later than 23 weeks of pregnancy.
Non invasive examination is a test to check whether the fetus is developing normally, which is somewhat similar to the purpose of Down syndrome screening, but the two are different. The non-invasive examination has a wider range of content than Down's screening and can better ensure normal fetal development. So women should not only undergo Down syndrome screening without non-invasive testing, as this is not good for themselves and the fetus.
