New blood test could replace surgery for endometriosis diagnosis
NCT ID NCT07006987
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new blood test called HerResolve™ to see if it can accurately detect endometriosis in women aged 18 to 49 who have symptoms like pelvic pain or abnormal bleeding. About 100 participants will give a blood sample before their scheduled laparoscopy (a surgical procedure) to compare results. If successful, this non-invasive test could help diagnose endometriosis faster and avoid unnecessary surgeries.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Females aged 18 to 49 with mild to severe symptoms of pelvic pain and/or abnormal bleeding. * Diagnostic laparoscopy is scheduled with histology on any visually suspected endometriosis, and all reports (surgical and pathology) to confirm a positive result. If no visually suspicious endometriotic lesions are seen, biopsies from random areas during the laparoscopy procedure to confirm a negative histopathology result. * Blood drawn during secretory or proliferative phase of the menstrual cycle * Provide written informed consent to participate in the study and provide medical history on medications. Exclusion Criteria: * Patients who object to medical history collection and data requests * Patients with cancer and/or undergoing chemotherapy and/or radiotherapy * Patients who are unable or do not undergo laparoscopic surgery * Patients participating in additional interventional clinical studies * Pregnant, lactating, or subjects who are not healthy enough for blood donation. * Blood drawn during menses or ovulation phase of menstrual cycle * Females who are post-menopausa
