Test Details
Methodology
Next Generation Sequencing: Identifies genetic variants, including small nucleotide variants (SNVs), insertions, deletions and copy number variants (CNVs).
Result Turnaround Time
14 - 21 days (In some cases, additional time may be required for confirmatory or reflex tests.)
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
This test is used for carrier and diagnostic testing for Wilson disease.
Special Instructions
If requesting full gene sequencing for multiple genes, order GeneSeq® PLUS [482370].
To test fetal specimens, including cord blood, order GeneSeq® PLUS, Fetal Analysis [482389].
Test orders must include an attestation that the provider has the patient's informed consent for genetic testing.
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.
