Genetic Testing for Adults
Tests
Genetic tests for adults can vary greatly: some assess hereditary diseases or polygenic risk, others evaluate the body's reaction to drugs, and some commercial tests analyze genetic variants related to nutrition, sports, skin, or other traits. Comprehensive genome-wide and other extensive tests are also offered.
Risk Result is Not a Diagnosis
The risk of many common diseases is not determined solely by genetics. A polygenic risk score summarizes the influence of many genetic variants, but its significance depends on the method, the population studied, and other health factors. An increased genetic risk does not mean the disease will necessarily develop, and a lower risk does not completely eliminate the possibility.
Genome-wide studies can detect many variants, some of which may not have clear clinical significance or may be unrelated to the initial reason for testing. Therefore, before undergoing an expensive or very extensive genetic test, it is worth clearly defining the expected outcome and how the result would influence further decisions.
If the test is conducted due to disease symptoms or a strong family history, diagnostic genetic testing and consultation with a geneticist are often more appropriate than a general commercial risk test.
