Patient's question:
I just finished checking the non-invasive DNA test. If this test is normal, do I not need to do any other tests, or are there still some tests I need to undergo?Doctor's answer:
Non-invasive deoxyribonucleic acid (DNA) is an emerging testing procedure in recent years, primarily used for prenatal examinations of pregnant women. Non-invasive prenatal testing (NIPT) requires only a blood sample from the pregnant woman and utilizes next-generation DNA sequencing technology to sequence free DNA fragments in the mother's peripheral plasma (including fetal free DNA). Bioinformatics analysis of the sequencing results is then performed to obtain fetal genetic information, thereby detecting whether the fetus has one of three major chromosomal disorders: Trisomy 13, Trisomy 18, and Trisomy 21.
