Patient's question:
I recently plan to have a non-invasive test, but I don't know which department to register for it. Can I eat before the test? What are the precautions I need to take?Doctor's answer:
Prenatal screening refers to the use of simple, feasible, and minimally invasive screening methods to identify high-risk groups among pregnant women who may have certain congenital defects and genetic diseases for further definitive diagnosis. Non-invasive prenatal testing (NIPT) requires only a blood sample from the pregnant woman. It utilizes next-generation sequencing technology to sequence free fetal DNA fragments in the mother's peripheral plasma (including fetal free DNA) and performs bioinformatics analysis on the sequencing results to obtain fetal genetic information, thereby detecting whether the fetus has three major chromosomal diseases. Fast in the morning on an empty stomach, do not eat anything, and call the number of the genetic center.
