Patient's question:
I am 33 years old this year and am currently 31 weeks pregnant. Recently, my husband took me to the hospital for a thorough prenatal check-up. The doctor recommended that I have a non-invasive DNA test. I want to know how to do the non-invasive DNA test during prenatal care and whether it has any side effects on the child? The help I need: How is the non-invasive DNA test done during prenatal care? Does it have any side effects on the child?Doctor's answer:
Generally, between weeks 15 and 20 of pregnancy, a Down syndrome screening should be done. Down syndrome screening is a test for chromosomal abnormalities such as trisomy 21 and trisomy 18. If this test shows any issues, an amniocentesis may be performed. DNA screening is similar to Down syndrome screening—it is also a screening test. It primarily involves taking blood from the pregnant woman for testing, and it has no side effects on the fetus, but the cost is relatively high. The above advice is for the question "How is non-invasive prenatal DNA testing done? Does it have side effects on the child?" I hope it helps you. Wishing you good health!
