Use

This test is used for diagnostic testing for arrhythmias, including atrial fibrillation, long QT syndrome, catecholaminergic polymorphic ventricular tachycardia, arrhythmogenic right ventricular dysplasia/cardiomyopathy and Brugada syndrome. It also is used for presymptomatic testing for family members.

Special Instructions

Not provided.

Limitations

Technologies used do not detect germline mosaicism and do not rule out the presence of large chromosomal aberrations including rearrangements and gene fusions, or variants in regions or genes not included in this test, or possible inter/intragenic interactions between variants or repeat expansions. Variant classification and/or interpretation may change over time if more information becomes available. False positive or false negative results may occur for reasons that include: rare genetic variants, sex chromosome abnormalities, pseudogene interference, blood transfusions, bone marrow transplantation, somatic or tissue-specific mosaicism, mislabeled samples or erroneous representation of family relationships. This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
