Important Information

The Custom Slice Xpanded® Priority (trio preferred) is an exome sequencing test with analysis limited to client selected genes with a prioritized turnaround time (TAT) of approximately 3-4 weeks. Because of the rapid TAT, blood or DNA samples on the proband and both biological parents must be submitted at the same time, along with clinical information, in order to begin testing. This test requires pre-approval by GeneDx via provider submission of one or more genes. Please email [email protected] prior to sending in samples.
