Genetic testing is a medical test that examines genes, the DNA that carries genetic information, to find changes or abnormalities that might cause or increase the risk of certain health conditions. This testing can identify genetic disorders, evaluate the risk of inherited diseases, or provide information about how an individual's body might respond to specific treatments. The tests are typically performed using samples of blood, saliva, or other tissues. Results can help in diagnosing conditions, making appropriate treatment decisions, and understanding family health risks.
