Special Instructions

Test orders must include an attestation that the provider has the patient's informed consent for genetic testing. For family tests involving known mutations, submit the result report of the initial tested patient if not performed at a LabCorp facility. Subsequent family members are tested for the specific mutation found in the initially tested patient.

Limitations

This method does not reliably detect mosaic variants, large deletions, duplications, inversions, or other rearrangements, nor deep intronic variants. It may be affected by allele-dropout and doesn't allow the determination of exact numbers of T/A or microsatellite repeats. The test does not conclude if two heterozygous variants are on the same or different chromosome copies. The performance characteristics were determined by Labcorp, but the test is not cleared or approved by the Food and Drug Administration.
