A new Australian study identifies biological markers in ME/CFS patients, including energy deficits and immune and vascular issues, paving the way for better diagnosis.

A new Australian study finds multiple biological abnormalities in people with ME/CFS, including cellular energy stress, impaired immune cell maturity, and blood vessel dysfunction. Analyzing blood from 61 patients and healthy controls, researchers detected elevated AMP and ADP levels indicating reduced ATP production, fewer mature immune cells, and altered plasma proteins tied to vascular health. Using machine learning, they identified seven potential biomarkers linked to ME/CFS, offering hope for faster, more accurate diagnosis and improved patient outcomes.
