Endometriosis Diagnosis: New Tests & What to Do Now

You’ve been to three doctors. You’ve been told “it’s just a bad period” or “your pain is normal.” But you know something isn’t right. The cramps are debilitating. The pain radiates down your legs. Your periods control your life, not the other way around. If this sounds familiar, you’re not alone — and you’re not wrong to keep pushing for answers.

Here’s the thing: getting an endometriosis diagnosis takes an average of 7 to 10 years globally. In the United States, estimates range from 4 to 11 years. That’s a decade of pain, frustration, and being told your symptoms are normal. But the landscape is shifting. In July 2026, the UK’s National Institute for Health and Care Excellence (NICE) approved two new non-invasive tests that could speed up diagnosis. The headlines are exciting — but the reality is more complex, especially if you live in the US.

This article breaks down what’s actually happening with new tests, what’s hype, and — most importantly — what you can do right now if you suspect you have endometriosis.

Why Does an Endometriosis Diagnosis Take So Long?

Let’s be honest: the current diagnostic process is frustratingly slow. A large 2026 study of 837 patients across 11 hospitals in the Netherlands found a median diagnostic delay of 7 years. Another French study of nearly 7,000 women reported an average delay of 10 years. In the US, estimates range from 4 to 11 years.

Why does it take so long? A few reasons:

• Symptoms are often dismissed. Many women are told their pain is normal or that they have a low pain tolerance. A 2025 UK study found that having a partner present during appointments can actually legitimize symptoms in the eyes of healthcare providers — which says a lot about how women’s pain is often not taken seriously on its own.
• Symptoms overlap with other conditions. Endometriosis can mimic IBS, ovarian cysts, and pelvic inflammatory disease. This makes it hard to pinpoint without specialized testing.
• Imaging can’t see most endometriosis. As Dr. Megan Wasson from Mayo Clinic explains, most endometriosis is superficial and simply doesn’t show up on ultrasound or MRI. A normal scan does not mean you don’t have it.
• Racial disparities are real. A 2025 study found that Black adolescents were 80% less likely to receive diagnostic laparoscopy than their White peers. These inequities start early and persist into adulthood.

How Is Endometriosis Diagnosed Right Now?

Before we talk about what’s new, let’s be clear about what’s current. The current diagnostic pathway for endometriosis typically looks like this:

1. Pelvic exam — Your doctor feels for cysts or tender spots. But many women with endometriosis have a normal pelvic exam.
2. Imaging — Ultrasound or MRI can sometimes spot endometriomas (ovarian cysts caused by endometriosis), but they miss superficial disease.
3. Medication trial — Some doctors prescribe hormonal birth control or GnRH agonists. If your pain improves, endometriosis is likely — but this is not a definitive diagnosis.
4. Diagnostic laparoscopy — This is the only way to confirm endometriosis. A surgeon makes small incisions in your abdomen and inserts a camera to look for endometrial-like tissue. If they find it, they can often remove it during the same procedure.

The problem? Laparoscopy is surgery. It requires anesthesia, recovery time, and carries risks. It’s also expensive and not always covered by insurance. No wonder women want a simpler option.

What New Tests Are on the Horizon?

Here’s where things get interesting. On July 7, 2026, NICE in the UK approved two new non-invasive tests for use in primary care. But — and this is important — they were approved for a 3-year evidence-collection period, not as fully validated standalone diagnostics. Let’s look at each one.

Endotest: The Saliva Test

Endotest analyzes your saliva for a specific pattern of 109 microRNAs — tiny molecules that regulate gene expression. A 2023 study published in NEJM Evidence found that this saliva-based miRNA test had 96.2% sensitivity and 95.1% specificity in a population where endometriosis was common (79.5% of participants had it).

Those numbers sound amazing, right? Here’s the catch: a test performs best in a population where the condition is already common. When you move it into a general population where fewer people have endometriosis, the positive predictive value — the chance that a positive result actually means you have the disease — drops. That’s exactly what the 3-year NICE evidence collection aims to figure out.

EndoSure: The Gut Signal Test

EndoSure takes a different approach. According to news reports, it uses sensor pads placed on your abdomen to measure electrical signals from your gut. The idea is that endometriosis affects the nerves and muscles in your pelvic area, creating a distinct electrical signature. Like Endotest, it’s an adjunctive tool — meant to be used alongside standard clinical practice, not to replace it.

What Else Is in the Pipeline?

Beyond these two tests, researchers are exploring several other non-invasive diagnostic methods:

• Blood tests — Researchers are studying blood-based biomarkers like cell-free DNA methylation patterns. These are promising but still in early research stages. For a closer look at one promising approach, read our coverage of the endometriosis blood test with 95% accuracy.
• Menstrual effluent analysis — A 2026 review of 35 studies found that analyzing menstrual blood for certain markers (like aromatase mRNA) showed diagnostic accuracy as high as AUC 0.977. But prospective validation is still needed before this can be used clinically.
• Cervical microbiome profiling — Early research suggests that changes in cervical bacteria may signal endometriosis.

How to Advocate for Yourself During the Diagnostic Process

While we wait for new tests to reach the US, there’s a lot you can do right now to speed up your own diagnostic journey. Here’s what the research and experts recommend.

1. Start a Symptom Tracker

This is the single most powerful tool you have. Track the following for at least 2-3 months before your appointment:

• Pain level (1-10 scale) each day of your cycle
• Pain location (lower back, pelvis, legs, during bowel movements)
• Bleeding pattern (heavy flow, clots, bleeding between periods)
• Other symptoms (fatigue, bloating, nausea, painful bowel movements, pain during sex)
• What helps and what doesn’t (heat, ibuprofen, rest, movement)
• Days of missed work or social activities — this quantifies the impact

Bring this tracker to every appointment. It turns your subjective experience into objective data that doctors can’t easily dismiss.

2. Find the Right Doctor

Not all gynecologists are equally experienced with endometriosis. Look for a specialist who:

• Lists endometriosis as a clinical focus
• Performs minimally invasive gynecologic surgery (MIGS)
• Is affiliated with a center of excellence for endometriosis
• Has experience with excision surgery (not just ablation)

Organizations like the Endometriosis Foundation of America and the Center for Endometriosis Care offer provider directories.

3. Bring a Support Person to Appointments

Research from the UK found that having another person present — especially a male partner — can legitimize symptom severity in the eyes of healthcare providers. This shouldn’t be necessary, but it’s a practical strategy that works. Bring a friend, partner, or family member who can help you articulate your symptoms and advocate for you.

4. Know What to Ask

Here are specific questions to bring to your appointment:

• “Could my symptoms be endometriosis?”
• “What diagnostic steps do you recommend?”
• “If imaging is normal, does that rule out endometriosis?” (Answer: no)
• “Would a diagnostic laparoscopy be appropriate for me?”
• “Can you refer me to a specialist who performs excision surgery?”

What Can You Do for Pain While Waiting?

The diagnostic limbo is hard. Here are evidence-supported strategies that may help manage symptoms while you wait for answers:

• Anti-inflammatory diet — Focus on whole foods, omega-3s (salmon, walnuts, flaxseeds), and plenty of vegetables. Some women find that reducing red meat, dairy, and gluten helps, though the evidence is mixed.
• Pelvic floor physical therapy — This can help relax the pelvic floor muscles that often tighten in response to chronic pain. Many women find significant relief.
• Heat therapy — A heating pad or warm bath can help relax cramping muscles.
• Over-the-counter anti-inflammatories — NSAIDs like ibuprofen or naproxen can help, but talk to your doctor about long-term use.
• Gentle movement — Yoga, walking, and stretching can help without aggravating pain.

The Bottom Line

The news about new endometriosis tests is genuinely exciting. After decades of relying solely on surgery for diagnosis, we’re finally seeing progress toward non-invasive options. But the reality is that these tests aren’t available in the US yet, and even in the UK, they’re still being evaluated.

Here’s what I want you to take away: you don’t have to wait for new tests to take action. Start tracking your symptoms today. Find a specialist who takes you seriously. Bring a support person to appointments. Ask the right questions. Your pain is real, and you deserve answers — whether those come from a saliva test in 2028 or a laparoscopy next month.

The diagnostic landscape is changing. But you don’t have to wait for it to change to start advocating for yourself.
