End Endometriosis Diagnosis: Persistent Delays and Emerging Tests
9/5/2026, 9:04:45 PM
Historical and Social Context
Endometriosis, a chronic inflammatory disease where tissue resembling the uterine lining grows outside the uterus, appears in medical texts from antiquity. Early writings noted severe pelvic pain, painful periods and infertility, while cultural interpretations framed such symptoms as “hysteria.” Modern pathology emerged in the 1860s with Karl von Rokitansky’s lesion descriptions and was formalized by John A. Sampson, who coined the term “endometriosis” in the 1920s and proposed retrograde menstruation as a causal hypothesis.
Scale of the Condition and Diagnostic Lag
Global estimates place endometriosis in roughly one-in-ten women of reproductive age, about 190 million worldwide. The World Health Organization reports diagnosis can take four to twelve years; other studies cite an average delay of seven to ten years from symptom onset to confirmation. In the United States, patients often experience years of normalising period pain, contributing to delayed care.
New Non-Invasive Tests Abroad
Two non-invasive diagnostics are now used outside the United States. The half-hour EndoSure test measures gut electrical signals via abdominal sensor pads, while the Endotest assay analyses saliva for micro-RNAs indicative of endometriosis, delivering results in two to three weeks. The United Kingdom’s national health advisory body has issued draft guidance to trial both tests within the NHS for three years while evidence accumulates.
Dr. Mark Noar, founder of the Maryland-based EndoSure company, says an FDA application is being prepared. French firm Ziwig is pursuing a laboratory-developed-test pathway to make Endotest available in U.S. certified labs. Both companies acknowledge the tests are intended as adjuncts, not replacements, for imaging and surgical confirmation.
State-Level Task Force Initiative
In Massachusetts, legislators and clinicians are proposing a dedicated endometriosis task force to examine gaps in awareness, diagnosis, treatment, research and access to care. Representative Lindsay Sabadosa, who has heard repeated constituent complaints of dismissed symptoms, helped launch the effort. Dr. Malcolm Mackenzie, a New England surgeon, warned that the disease is likely underdiagnosed beyond the reported 10 percent prevalence. Patient advocate Amanda Berg, diagnosed after a 20-year symptom history, described the emotional toll of having her pain dismissed.
Expert Guidance for Patients
Clinicians stress proactive self-advocacy. Dr. Drorit Or of Mount Sinai West advises patients to keep detailed pain diaries to facilitate informed consultations. Dr. Megan Billow of the Cleveland Clinic notes that many health-care providers lack specialized knowledge of endometriosis, contributing to diagnostic wandering.
Prof. Zozo Nene, head of the reproductive and endocrine unit at the University of Pretoria and Steve Biko Academic Hospital, emphasized that any pain disrupting daily activities warrants assessment and that delayed diagnosis can erode educational, career and fertility opportunities.
Conflicting Reports & Gaps
Sources differ on the exact length of diagnostic delay: WHO cites a four-to-12-year range, while academic literature frequently reports a seven-to-10-year average. Prevalence estimates also vary; most sources state a 10 percent rate, while Dr. Mackenzie suggests the true figure could be “significantly higher,” without quantitative support.
What’s Next
The EndoSure company plans to submit its FDA application in the coming months, and Ziwig is finalising laboratory-developed-test protocols for U.S. distribution. Massachusetts is vetting candidates for its task force, including medical professionals and lived-experience representatives. In France, the PRECURSOR research project will enrol adolescent girls with severe menstrual pain to evaluate early-intervention strategies aimed at preventing chronic pelvic pain and endometriosis development.
These developments aim to shorten the diagnostic journey, expand therapeutic options and reduce the lifelong burden of endometriosis for millions of women worldwide.
