Can a Blood Test Distinguish ME/CFS?

A genome-wide epigenetic blood test using chromosome conformation profiling reported high accuracy in distinguishing ME/CFS from healthy controls.

A recent study published in the Journal of Translational Medicine explored the potential of three-dimensional chromosome conformation profiling for diagnosing Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Analyzing blood samples from 47 patients and 61 controls, researchers identified a panel of 200 chromosome conformation markers. The developed Episwitch Chronic Fatigue Syndrome test demonstrated high sensitivity (92 percent), specificity (98 percent), and accuracy (96 percent). These findings linked immune pathways to ME/CFS and suggested that epigenetic profiles could guide personalized treatment strategies.
