    Test Details


    Use

    Whole exome sequencing (WES) is a genetic test used to identify a hertiable cause of disorder. This test should be used in cases of WES DUO or TRIO sequencing where the mother can be used as a comparator to inform the diagnosis of the proband.


    Limitations

    This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
