Genetic Testing For Long QT Syndrome

Hawaii rates for HCPCS 81280

Genetic testing on a blood or saliva sample for long QT syndrome, an inherited fault in the heart's electrical system that can cause fainting, seizures or sudden cardiac arrest, often during exercise or sudden fright. This is the broad version that examines the genes known to cause the condition, rather than checking only for a change already identified in the family.
