Remarks

Documentation of the familial gene variants(s) is required to perform targeted sequencing. Submit a copy of a relative's laboratory test report documenting the gene and specific variants(s) for which testing is requested.
Submit a positive control with the patient specimen for appropriate interpretation, order Sequencing Control (test code 0051650). Samples tested without a familial positive control may be subject to a disclaimer.
Testing will begin upon receipt of all necessary components, including an original laboratory report detailing the familial variant(s) to be tested and a familial positive control sample.
