Genetic screening is a medical test that examines an individual's DNA to identify genetic disorders or predispositions to certain diseases. This process can help detect conditions like cystic fibrosis or sickle cell anemia before symptoms appear, allowing for early intervention and management. There are different types of genetic screening, including carrier screening, which checks if a person carries a gene for a specific disorder, and prenatal screening, which assesses the fetus for genetic abnormalities. These tests can provide valuable information for families planning for the future and help healthcare providers offer personalized care.
