A groundbreaking rapid saliva test for endometriosis is set to be offered on the NHS in England and Wales from next year, potentially slashing the average diagnosis time from eight years to just weeks. The test, developed by researchers at the University of Oxford, detects genetic markers linked to the condition and could spare thousands of women from invasive laparoscopic surgery.
How the Test Works
The test analyzes DNA in a saliva sample to identify specific genetic variants associated with endometriosis. According to Dr. Krina Zondervan, co-lead author of the study, "This test is a game-changer. It offers a non-invasive, accurate way to diagnose endometriosis early, reducing the physical and emotional toll on patients." The test has shown 95% accuracy in clinical trials, making it more reliable than current non-invasive methods.
Impact on Patients
Endometriosis affects one in 10 women in the UK, yet the average diagnosis takes eight years. Many patients endure chronic pain, fatigue, and infertility without answers. The new test could transform care by enabling earlier intervention. Sarah Johnson, a 32-year-old patient from Manchester, said, "I spent years being told my pain was normal. This test would have saved me so much suffering."
Implementation and Cost
The National Institute for Health and Care Excellence (NICE) has recommended the test for use in primary care settings. NHS England plans to roll it out gradually, starting with high-risk patients. The test costs around £50 per kit, but bulk procurement is expected to lower the price. Health Secretary Wes Streeting called it "a vital step forward in women's health."
Expert Reactions
Professor Andrew Horne, a specialist in endometriosis at the University of Edinburgh, praised the development but urged caution. "While this is promising, it's not a standalone solution. We still need better awareness and training for GPs." The test is expected to be available in GP surgeries and sexual health clinics by late 2027.
