Sunquest Code:COLHERCoPath Code:COLHER
Epic Code:LAB8158Epic Name:Hereditary Cancer Colon
Methodology:Next generation sequencing.
Turnaround Time:Testing is performed Mon-Fri; results are reported within 4-6 weeks.
Special Instructions:Gene(s) or the name of the panel should be indicated in the comment section of EPIC order.
A signed informed consent in the patient's medical record is required. The consent should not be sent to the laboratory. The link to the Genetic Testing Consent Form is provided as a convenience for the providers and genetic counselors.
Bone Marrow Transplant Patients: If a patient is the recipient of an allogeneic transplant, this test must be done on a pre-transplant sample. Contact the Molecular Diagnostic lab to see if a pre-transplant sample is available.
