Patient's question:
Hello, I am 31 weeks pregnant. To better combine prevention and treatment, I think it is necessary to do some tests for the fetus. If so, how are the main tests for some essential prenatal examinations, such as genetic diseases? Thank youDoctor's answer:
Hello; With the continuous development of technology, in addition to prenatal screening, non-invasive prenatal genetic testing can now be used to detect Down syndrome and abnormalities in chromosomes 18 and 13. Non-invasive prenatal genetic testing can identify over 99% of Down syndrome-affected fetuses. Like prenatal screening, it only requires a blood draw from the arm for testing, avoiding the increased risk of miscarriage associated with amniocentesis or chorionic villus sampling. For women of advanced maternal age or those at high risk for prenatal screening, non-invasive prenatal genetic testing is an alternative choice for undergoing amniocentesis.It is recommended that you visit the hospital for prenatal check-ups during pregnancy. Ultrasound and other tests can help determine if the fetus is developing normally.
