New Study: Researchers Explore if Blood Tests Could Help Improve Endometriosis Detection

March is Endometriosis Awareness Month

PHOENIX, Ariz. (March 30, 2026 ) – A new study aimed at finding an easier way to diagnose endometriosis has a surgeon with Dignity Health St. Joseph's Hospital and Medical Center discussing the impact it could have on patients.

The study, published recently by the Journal of Minimally Invasive Gynecology, used blood tests to detect endometriosis in a group of nearly 300 women. Researchers found success rates were high, with the tests accurately detecting the disease in 80 percent of those confirmed to already have it. The data also shows  61.5 percent of the positive cases that were discoverable with this new method had been missed by MRIs and ultrasounds.

According to Sheena Galhotra, MD, a Dignity Health minimally invasive gynecological surgeon, though the blood test needs to be studied further, overall the outlook is positive for this new detection method. 

“A blood test for endometriosis would be a major step forward,” Dr. Galhotra says. “Right now, this research represents an encouraging direction, but more validation is needed before it can change how we diagnose patients. The goal is to shorten the times it takes patients to get answers and begin treatment.”

 Endometriosis is a condition in which  tissue grows outside of the uterus or on surrounding organs, causing intense period cramps, heavy bleeding, infertility, and non-menstrual pelvic pain, among other issues. Despite the chronic disease impacting 1 in 10 women of reproductive age, more awareness is still needed. 

“For many patients, receiving an endometriosis diagnosis is an emotional moment,” shares Dr. Galhotra. “It validates the symptoms and pain they’ve been experiencing. I take great pride in advocating for my patients dealing with this  condition and look forward to finding a more efficient way to  provide them answers and relief.”
