Test Details


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 parental samples are unavailable and an additional family member can be used as a comparator to inform the diagnosis of the proband.


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