New rapid diagnostic tests for endometriosis are set to revolutionise the way doctors diagnose this debilitating condition in England and Wales. The National Institute for Health and Care Excellence (NICE) has provisionally approved two tests, EndoSure and Endotest, which could dramatically cut the average diagnosis time from nine years and four months to just a few weeks.
Endometriosis affects around one in ten women of reproductive age, causing severe period pain, bowel and urinary discomfort, and painful sex. Despite its widespread impact on physical and mental health, women often face lengthy waits for a diagnosis, with delays exacerbated by invasive diagnostic procedures such as ultrasound scans, MRI, or laparoscopy – an operation involving a camera inserted through a small incision in the abdomen.
The new tests offer a welcome respite from these difficulties. Endotest involves providing a saliva sample, which is then analysed for specific biological markers indicating endometriosis. The results are returned to the GP or other healthcare professional to guide further diagnostic and care decisions. In contrast, EndoSure detects the condition by measuring electrical signals in the gut, requiring women to fast for six to eight hours beforehand and drink water during a 45-minute test.
NICE has issued a draft recommendation granting approval for these tests for three years, allowing further evidence on their effectiveness and utility in real-world clinical settings. It's essential to note that these tests are designed for use after normal clinical examinations and inconclusive or negative imaging results, rather than as standalone diagnostic tools. Women should consult their GP for medical advice or call NHS 111.
Dr Gail Busby, a consultant gynaecologist at Manchester University NHS Foundation Trust, hailed the potential of these tests to transform care for women with endometriosis: "These innovative tests have the potential to revolutionise the diagnosis and treatment of endometriosis, improving patient outcomes and quality of life."
NICE's healthtech programme director, Dr Anastasia Chalkidou, highlighted the significant delays in diagnosing endometriosis, particularly among individuals from ethnically diverse communities, which can extend to 11 years. The introduction of these rapid diagnostic tests is expected to alleviate some of this burden and bring hope to thousands of women affected by this condition.
