Patient's question:
High-risk pregnant woman, 37 years old, 16 weeks and 4 days pregnant, underwent prenatal non-invasive testing, with results indicating low risk, details can be found in the test report.Doctor's answer:
Advanced maternal age is a high-risk factor for fetal chromosomal abnormalities. Compared to amniocentesis, the advantage of non-invasive testing is that it only requires drawing maternal blood, eliminating the risks of miscarriage, infection, and other potential complications associated with amniocentesis. However, its drawback is that it can only test the three pairs of chromosomes most likely to have issues, which are the three pairs you see in your results. In contrast, amniocentesis can examine all 23 pairs of chromosomes, making it more comprehensive. You can wait for the mid-pregnancy ultrasound screening results. If the ultrasound findings or any other issues arise during subsequent regular prenatal exams, further testing may still be necessary.
