Researchers say they have created the first accurate blood test to detect myalgic encephalomyelitis, or chronic fatigue syndrome (ME/CFS).
The test, developed by scientists at the University of East Anglia and Oxford Biodynamics, showed 92% sensitivity and 98% specificity.
It identifies unique DNA-folding patterns found only in ME/CFS patients, offering a potential breakthrough for faster diagnosis.
“Many patients have gone undiagnosed for years,” said lead researcher Prof Dmitry Pshezhetskiy. “Our discovery could change that.”
The study, published in Journal of Translational Medicine, analysed blood from 47 patients and 61 healthy adults.
Experts welcomed the progress but urged caution. “The findings need independent validation,” said Dr Charles Shepherd of the ME Association.
Prof Chris Ponting called the claims “premature,” warning that the test must be tested on broader patient groups and could cost around £1,000.
If confirmed, the test could mark a major step forward for ME/CFS patients long dismissed or misdiagnosed.
