Non-invasive diagnostics of endometriosis: review of modern biomarkers of peripheral blood and endometrium

Endometriosis is a chronic progressing estrogen-dependent disease with a high incidence among females characterized by pelvic pain (40-80%) and infertility (25-80%). Aim. To analyze and estimate the modern literature data on the possibility of using potential biomarkers of endometriosis in its non-invasive diagnostics. In recent years, researchers have made significant advances in understanding the disease-specific molecular pathways that regulate the development of ectopic foci of endometriosis, by examining the blood, peritoneal fluid, and eutopic endometrium in women with the disease. Along with understanding the pathophysiology of endometriosis, the question of finding an adequate biomarker that will provide an effective early non-invasive diagnosis of endometriosis and, accordingly, preserve the reproductive health of millions of women, remains relevant. Conclusion. Most reasonable in diagnostics of endometriosis is a combination of different biomarkers that also minimizes false positive and negative results in differential diagnosis.
