A 37-year-old pregnant woman is of advanced maternal age, and amniocentesis is necessary for patients with risk factors such as advanced age, fetal malformations, and a family history of inherited diseases. In addition to the high-risk groups suitable for prenatal screening, amniocentesis is also recommended for prenatal diagnosis of excessive amniotic fluid, low amniotic fluid, suspected fetal malformations, chromosomal malformations in one of the spouses, family history of inherited diseases, and prenatal diagnosis at the expected age of 35 years old or older, and usually the older the pregnant woman, the higher the risk of chromosomal abnormality in the fetus. Amniocentesis is one type of prenatal diagnosis and the most widely used. The rest include chorionic villus aspiration sampling and umbilical cord vascularization sampling, which can diagnose chromosomal anomalies, sex-linked genetic diseases, and inherited metabolic diseases. For pregnant mothers who are older than 35 years old or who have abnormalities in their labor tests, it is recommended to consult with a medical professional to see if there is a need to improve the relevant tests.
