Genetic testing is the diagnostic study of choice to definitively diagnose<unk>  cardiomyopathy.  While definitive, these techniques can be expensive and can be difficult to access.  If the mutation has already been identified in other family members, it is fairly efficient to test for that isolated mutation. Once HCM has been identified in a family, immediate testing of all family members will help to identify those at risk.
