What test would be performed if you remove a piece of the placenta to study for abnormalities?

If a piece of the placenta is removed for study, the test performed is typically called placental biopsy or chorionic villus sampling (CVS), depending on the timing of the procedure. This test allows for genetic testing to identify chromosomal abnormalities, infections, or other placental conditions. The sample can be analyzed for specific genetic disorders, such as Down syndrome or other congenital anomalies. Results from these tests can provide important information about the health of the fetus and potential risks.
