Researchers say they’ve developed the first accurate blood test for myalgic encephalomyelitis, also known as chronic fatigue syndrome (ME/CFS).
The test could transform diagnosis for patients who often go years without answers, relying only on symptoms for identification.
Led by Prof Dmitry Pshezhetskiy at the University of East Anglia, the study found distinct DNA-folding patterns unique to ME/CFS patients.
Testing 47 patients and 61 healthy adults, scientists achieved 92% sensitivity and 98% specificity, suggesting strong accuracy.
“This is a significant step forward,” said Pshezhetskiy. “We finally have a simple test that can reliably identify ME/CFS.”
However, experts urged caution. “These claims are premature,” said Prof Chris Ponting. “The test must be validated in independent studies.”
Dr Charles Shepherd of the ME Association called it “an important step,” but warned it must be tested across wider patient groups.
If confirmed, the breakthrough could offer earlier diagnosis, better care, and hope for millions affected by the debilitating illness.
