MCQs on Amniocentesis With Answers

A medical procedure used in the prenatal diagnosis of chromosomal abnormalities, sex determination and fetal infections is known as Amniocentesis. It is a diagnostic procedure undergone during pregnancy, typically to check the baby’s chromosomal setup. Occasionally, the test is performed to examine for other pregnancy infections/diseases or genetic disorders. The test is performed by collecting the amniotic fluid containing foetal cells and other substances such as alpha foetal protein.
