Pregnant women need to have a healthy body and a positive mindset when giving birth. In addition, prenatal check ups should also be conducted on time, and there are many items to be checked, including non-invasive DNA. So, how late should non-invasive DNA be done?
Non invasive DNA testing should not exceed 26 weeks of pregnancy, and the testing time is generally between 12 and 24 weeks. If the previous Down syndrome screening was low-risk, there is no need to undergo this screening. If Down syndrome screening is considered high-risk, non-invasive DNA testing is required. If the risk of non-invasive DNA testing results is low, it means that the fetus can grow healthily. Pregnant women do not need to worry too much and can patiently wait for the arrival of new life. Pay attention to fetal heart rate monitoring in the later stages of pregnancy.
Pregnant women do not need to go on an empty stomach for non-invasive DNA testing. Some pregnant women have heard that blood tests are needed and are worried about not being able to eat. And for this examination, it is not necessary to do it on an empty stomach. Pregnant women can have breakfast before the examination to avoid low blood sugar, which is not conducive to their health. We should focus on a light diet. Also, it is important to rest well before the examination to ensure its accuracy.
Finally, women should pay attention to wearing loose clothing before the examination. At the same time, pregnant women should also regulate their emotions and not be too nervous or worried. If they undergo the examination in an overly anxious state, it may actually affect the results.
