Doctor's answer (1)
Dr. Zhang Jianhai
Non-invasive prenatal DNA testing (NIPT) primarily screens for fetal chromosomal abnormalities, such as trisomy 21 (Down syndrome). NIPT boasts a relatively high accuracy rate. If conventional serum screening (e.g., the “triple” or “quadruple” test) yields a high-risk result, NIPT is recommended for further evaluation. NIPT involves drawing a blood sample from the pregnant woman and poses no risk to the fetus.
