Endometriosis, a reproductive condition affecting roughly 1 in 10 women worldwide, can now be detected through a non-invasive saliva test called Endotest, following approval from the National Institute for Health and Care Excellence (NICE) in the UK. According to Yale Medicine, women face an average wait of 11 years between their first symptoms and a formal diagnosis of the disease, which occurs when uterine tissue grows outside the uterus to cause chronic pain, cramping, and complications like a frozen pelvis or infertility.
How Endotest Detects Endometriosis From Saliva Samples
The Endotest diagnostic tool checks a patient’s saliva sample for specific microRNAs that indicate whether endometriosis is present, according to NICE. While NICE noted that the product is not meant to serve as a standalone diagnostic tool, it has received approval for use in clinicians’ offices across England and Wales for a three-year period. Dr. Gail Busby, a consultant gynaecologist at Manchester University NHS Foundation Trust, stated in a press release that the test provides answers much earlier without requiring invasive surgery.
Before the introduction of saliva screening, diagnosing the condition required extensive medical workups. Dr. Sheeva Talebian, a board-certified reproductive endocrinologist, previously told The Post that patients often undergo colonoscopies, endoscopies, and abdominal MRIs yet still receive no clear findings. Talebian noted that endometriosis remains one of the most common missed diagnoses because doctors lack effective blood tests or imaging modalities to catch the disease in its early stages.
Did you know? Affecting approximately 10% of women globally, endometriosis symptoms extend beyond painful periods to include fatigue, joint pain, shortness of breath, irritable bowels, urinary frequency, and infertility.
Clinical Challenges and the Impact of Delayed Diagnosis
The progression of endometriosis does not always correspond to symptom severity, according to medical specialists. Talebian explained that in severe cases, chronic inflammation and scar tissue cause a condition known as a frozen pelvis, where the ovaries, bladder, and bowel fuse together and distort internal anatomy. Furthermore, the disease impacts fertility by diminishing ovarian reserve and physically blocking fallopian tubes.
Talebian stated she was haunted by how long “we’ve conditioned women to believe that debilitating pain is normal,” adding that even gynecologists may miss varying symptoms and refer patients to other specialists. By providing an alternative to prolonged diagnostic journeys, tools like Endotest aim to streamline clinical workflows. Busby noted that an earlier diagnosis frees up medical appointments and surgical slots for other patients waiting for care.
