Overview
Biomarkers are measurable signals in blood, urine, saliva, menstrual effluent, or tissue that may reflect the presence or activity of endometriosis. Researchers are studying proteins (such as CA-125 and cytokines), small RNAs, cell-free DNA, and microbiome patterns to enable earlier, less invasive detection, classify subtypes, and track treatment response. These tools are designed to complement clinical assessment and imaging, not replace them.
Right now, no single biomarker is accurate enough for routine diagnosis. Combination panels may perform better, and promising work includes menstrual effluent testing and multi-omics paired with machine learning. Learn what common labs can and cannot tell you today, how signals may vary across deep disease and endometriomas, and how results could integrate with Ultrasound and MRI. Because microbes and immune pathways are part of this story, the microbiome’s role connects with Gut Health, while inherited risk relates to Genetics.

Is there a reliable blood test that can diagnose endometriosis?
No FDA-cleared blood test can confirm or exclude endometriosis with high accuracy. Markers like CA-125, cytokines, or microRNA panels are nonspecific and influenced by menstruation and other conditions. Diagnosis still relies on history, exam, and targeted imaging such as Ultrasound and MRI, with surgery considered in select situations.
What does a high CA-125 mean if I have pelvic pain or an ovarian cyst?
CA-125 can be elevated with ovarian endometriomas, but also with menstruation, adenomyosis, fibroids, infection, and non-gynecologic issues. It can support clinical suspicion but cannot confirm endometriosis; trends are only useful when interpreted alongside symptoms and imaging.
Can menstrual blood tests diagnose endometriosis today?
Testing menstrual effluent for endometrial cells, proteins, or microRNAs is promising for noninvasive detection. These assays are still in research and not validated for routine care, so results should not replace clinical evaluation and imaging.
Do microbiome tests help with diagnosis or treatment decisions?
Studies show differences in gut and reproductive tract microbes in some people with endometriosis, but microbiome testing is not diagnostic yet. Focus on symptom-guided nutrition and GI care while research evolves; see Gut Health for evidence-based strategies.
Can biomarkers guide treatment choice or track whether therapy is working?
In research, biomarker panels may help personalize hormonal therapy, pain care, or timing of Surgery by stratifying inflammation or disease activity. For now, changes in symptoms, daily function, and imaging are the most reliable ways to monitor response; CA-125 trends may be followed in select cases such as large endometriomas.
