In order to identify these genetic predispositions, genetic tests have to be done through laboratory methods. There are currently seven methods of genetic testing: diagnostic testing, predictive and pre-symptomatic genetic tests, carrier testing, prenatal testing, newborn screening, pharmacogenomic testing, and research genetic testing. Diagnostic testing involves methods that are used to identify the disease that is affecting a person.
