Two New Tests Could Slash Endometriosis Diagnosis Time From Years to Weeks

For years, getting an endometriosis diagnosis felt like navigating a maze blindfolded, often taking a decade. But now, it looks like GPs in England and Wales are getting some much-needed navigational tools: two new non-invasive tests that could significantly cut down those agonizing wait times.

Endometriosis, for the uninitiated, is a condition that affects roughly one in ten women. It’s when tissue similar to the womb lining decides to set up shop outside the womb, causing chronic pain and a whole host of other issues. Imagine your internal organs having an uninvited, very painful guest.

No More Guessing Games?

The first new test is a spit test, which sounds exactly like what it is: a simple saliva sample that hunts for specific genetic markers. The second test is a bit more sci-fi: it measures electrical signals in the gut using sensor pads placed on the abdomen. Think of it as a low-key lie detector test for your insides, but for endometriosis.

These tests are currently recommended in new draft guidance for the NHS. The idea is to use them alongside standard check-ups, giving doctors a much clearer picture early on. Experts are already calling them a "game-changer," and considering the average nine-year wait for a diagnosis, that’s not an exaggeration.

Ami Robertson, 23, knows this wait all too well. She experienced endometriosis pain from age 16, only to be repeatedly told it was something else, like irritable bowel syndrome. "I started to doubt myself, wondering if it was all in my head," she shared. Ami eventually paid for private checks that confirmed her diagnosis and led to surgery. "No one should have to wait years to be believed."

Sharan Uppal, 46, had a similar uphill battle for her 15-year-old daughter, Simran. They shelled out for the gut test, which came back strongly positive. "It gave me the empowerment to go back to our GP and push for a referral," Sharan said. "That test opened doors for us to get Simran the help she needed."

The saliva test, charmingly named Endotest, is already in a pilot NHS study. The gut electrical signal test, Endosure, is part of a clinical study at the Worcestershire Acute NHS Hospital Trust. For the gut test, you just fast for a few hours, then drink some water during the 45-minute test. Which, if you think about it, is a small price to pay for answers.

GPs will be able to offer one or both tests, depending on availability and the watchful eye of an endometriosis expert. It's important to note these aren't meant to be the only diagnostic tools, but rather a much-needed shortcut. Currently, the go-to NHS diagnostic is a laparoscopy — a surgical procedure under general anesthetic. So, yes, a spit test sounds significantly more appealing.

Emma Cox, chief executive of Endometriosis UK, is understandably thrilled. But she also rightly points out that these tests are only as good as the education surrounding them. GPs and nurses will need to be well-versed to ensure quick access. Because nobody should have to fight for years just to be heard, well, believed.
