‘Game-changing’ spit test could shrink years-long wait for diagnosis of condition that affects 190M women

Endometriosis often traps women in a cycle of pain and medical uncertainty. Many patients face a wait of up to eleven years before receiving an accurate diagnosis. This delay occurs because the condition remains difficult to identify through standard blood tests or imaging. Symptoms like chronic pain and fatigue are frequently misattributed, leaving many to seek answers from multiple specialists without resolution.

A new saliva test called Endotest could change this timeline. The test identifies microRNAs in saliva that act as indicators for the presence of endometriosis. While it is not intended to serve as a standalone diagnostic tool, its approval for use in clinical offices across England and Wales represents a significant step for patients seeking earlier detection.

By shortening the diagnostic window, medical providers expect to free up clinical resources and surgical slots. This shift aims to reduce the burden on patients who previously endured long periods of testing without finding the cause of their symptoms. Early detection allows for earlier intervention, potentially preventing severe complications like internal organ fusion or fertility loss.

Medical professionals see this as a practical tool for primary care settings. It moves the needle away from invasive diagnostic procedures that were once the default for women experiencing persistent, unexplained reproductive health issues. As the medical community integrates these new screening options, the focus remains on addressing the long-term health impact of a condition that affects 190 million women globally.
