Genetic testing is a medical test that analyzes DNA, the chemical database that carries instructions for the body's functions. It can identify changes in chromosomes, genes, or proteins, helping to diagnose genetic disorders or assess the risk of developing certain diseases. This testing can be crucial for making informed health decisions and understanding inherited conditions. There are various types of genetic tests, including those for carrier screening, prenatal testing, and diagnostic testing. These tests can provide valuable information for individuals and families, guiding them in their healthcare choices and family planning. Advances in technology have made genetic testing more accessible and accurate than ever before.
