Genetic testing is a method used to identify changes in chromosomes, genes, or proteins that can contribute to the development of an inherited disorder. It is also used to confirm a diagnosis when a particular genetic condition is suspected based on an individual's symptoms and family history. Genetic testing can help determine a person's risk of developing certain diseases or conditions, guide treatment decisions, and inform reproductive planning. The results of genetic testing can have important implications for an individual's health and well-being, as well as for their family members.
