GI Test Service


This test service is available to United States residents only.

All submitted lab requisition forms must have a qualified* physician’s signature on the lab requisition form or the submitted sample will not be run/processed at the MicroGenDX Laboratory. To learn more CLICK HERE

*qualified: in this instance refers to a physician that is licensed to treat for the sample that is being submitted. Example: a Podiatrist can not treat for a UTI so they would not be qualified to sign a UTI test lab requisition form. The UTI test lab requisition form can only be signed by a Urologist, OBGYN or GP to qualify.

For assistance with finding a qualified physician in your area call our customer service center at 855-208-0019 and press 1.
