Test Code CPVTG Catecholaminergic Polymorphic Ventricular Tachycardia Gene Panel, Varies


Ordering Guidance


This test is intended for genetic screening for and diagnosis of catecholaminergic polymorphic ventricular tachycardia.

 

For comprehensive inherited cardiac arrhythmia genetic testing, order CARGG / Comprehensive Arrhythmia Gene Panel, Varies.

 

Customization of this panel and single gene analysis for any gene present on this panel are available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.

 

Targeted testing for familial variants (also called site-specific or known mutations testing) is available for the genes on this panel. See FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.
