Amniocentesis can detect diseases such as thalassemia and hemophilia. Amniocentesis is a relatively accurate test for the diagnosis of fetal abnormalities, including thalassemia and phenylketonuria, as well as hemophilia, chromosomal abnormalities, and pseudohypertrophic progressive muscular dystrophy. During pregnancy, amniocentesis is generally recommended for women based on their personal situation and family history. If amniocentesis is indicated, it should be performed between 16 and 22 weeks of pregnancy. Amniocentesis is an invasive test and pregnant women are advised to consult a specialist before undergoing the test.
