Carrier screening is a type of genetic test that helps check if a person carries a gene for a hereditary condition, even if they do not have symptoms of that condition. This test is often done before pregnancy or early in pregnancy to evaluate the risk of passing on genetic disorders to the child. For example, screening can identify carriers of conditions like cystic fibrosis or sickle cell disease. Knowing carrier status can help individuals make appropriate decisions about family planning and potential steps to manage or reduce the risk of these conditions.
