Don’t be too nervous if you have a high Down’s syndrome test. If the risk is moderate or high, it is necessary to continue with non-invasive DNA or amniocentesis to accurately determine whether the fetus has genetic problems. Non-invasive DNA is the extraction of maternal serum to accurately determine the condition of the fetus, while amniocentesis is the extraction of amniotic fluid to more accurately determine the condition of the fetus. The accuracy of non-invasive DNA and amniocentesis can reach more than 99%, which is the final result of the test.
