Changing the "scope" of diagnosing endometriosis: the new frontier of noninvasive markers.

Endometriosis affects 1 in 9 women, and diagnosis is often delayed using conventional laparoscopy. Noninvasive markers of endometriosis have the potential to enable earlier diagnosis, leading to more timely treatment and better surgical planning. This issue's Views and Reviews seek to summarize the current status of noninvasive markers of endometriosis. Experts in reproductive medicine with prior work in this field summarize the key literature on endometrial biomarkers, blood biomarkers, and advanced imaging, including ultrasound and magnetic resonance imaging. At present, there is no single definitive biomarker that can diagnose endometriosis with high sensitivity and specificity. Advancing endometriosis biomarkers beyond the discovery phase is challenging, and more work is needed. Clinicians who have an improved understanding of noninvasive imaging and biomarkers will be able to identify endometriosis earlier and more easily, allowing for prompt consideration of treatment options. We believe that continued research, innovation, and development will lead to improved diagnostic accuracy and guidance toward the best treatments for endometriosis-related pain and infertility.
