Gene tests or DNA tests are an important tool used to confirm or make diagnoses in certain disorders. They can also be used in order to establish parentage and an individual’s ancestry. Genetic testing looks at changes in chromosomes, genes and proteins, these changes are often associated with inherited disorders, and are used as a diagnostic tool with other clinical features.
Gene tests can confirm or rule out a suspected genetic condition or help calculate the chance of developing or passing on a genetic disorder. The technology used is always evolving and new gene tests are being discovered and developed.
