Genetic testing analyzes your DNA to identify changes in your genes, chromosomes, or proteins. These tests can provide information about your risk of developing certain diseases, your carrier status for genetic disorders, and how you might respond to certain medications. Types of Genetic Tests: Diagnostic testing: To confirm or rule out a specific genetic condition. Carrier testing: To determine if someone carries a gene for a genetic disorder that they could pass on to their children. Predictive and presymptomatic testing: To assess the risk of developing a genetic disorder in the future. Prenatal testing: To detect genetic abnormalities in a fetus during pregnancy. Newborn screening: To identify genetic disorders in newborns that can be treated early. Pharmacogenomic testing: To determine how a person's genes affect their response to medications.
