TIER-1 Diagnostic Test for Endometriosis

ENDOSURE is an accurate yet non-invasive diagnostic test for endometriosis. The ENDOSURE test uses an electroviscerography system (EVG), an analytical instrument that collects Gastro Intestinal Myoelectrical Activity (GIMA) signals from the abdomen through dry electrodes. The test detects endometriosis presence by measuring a GIMA pattern unique to endometriosis sufferers, known as the GIMA biomarker. Very similar to an electrocardiogram/EKG it’s easy to perform and provides a near-instant diagnostic result using simple, objective GIMA data.

Electroviscerography system (EVG) is an analytical instrument that collects myoelectrical activity signals from the gastrointestinal tract (GIMA).

ENDOSURE test records patient GIMA pattern over 30-minutes, then compares data to the GIMA biomarker of endometriosis, a known digital “fingerprint” of people who suffer from endometriosis.2,3

Patients generally book a separate consult with the test clinic’s attending clinician to review results, who can support your diagnosis of endometriosis and expedite disease management.

What is endometriosis?

When endometrial-like tissue grows in areas other than the uterus, it’s known as endometriosis. Endometrial tissue lines the uterus, thickens each month in response to hormones, and if pregnancy is not achieve will shed during menstruation and leave the body. Endometrial lesions also build up in response to hormones, but the tissue has nowhere to go during menstruation. This results in pain & inflammation, and eventually scarring & adhesions.

What Clinicians are Saying

“We’ve not seen any real movement in the treatments and the diagnosis of endometriosis for like two decades and now it’s all seems to be coming together. It’s a combination of the ENDOSURE test and the new drugs, which is going to change the management for many of these young women.”
- Dr. David Griffiths, Consultant Gynaecologist MB ChB, FRCOG

“ Until now we haven’t had a very good, simple, easy, quick, inexpensive screening test for endometriosis. Until now the only way to diagnose endometriosis definitively has been with a surgical procedure. We have the potential to crack that nut.

Larry Glazerman, MD, MBA
“If patients understand why they’re experiencing symptoms, it helps them cope, reduces stress, and creates closure so they can move forward with appropriate treatment. ENDOSURE testing provides that clarity in minutes rather than years.”
-Dr. Sarah Roth, ND
