Amniocentesis is a medical procedure used during pregnancy to diagnose certain genetic abnormalities or fetal infections, among other conditions. It involves the extraction of a small amount of amniotic fluid surrounding the fetus for analysis. However, amniocentesis is not used to test for disorders like malaria or typhoid. Instead, it is primarily employed to detect chromosomal abnormalities such as Down syndrome, thalassemia ,haemoplilia, sickle-cell anemia, etc., or genetic disorders in the developing fetus.
