Researchers say they’ve developed the world’s first reliable blood test to detect myalgic encephalomyelitis, or chronic fatigue syndrome (ME/CFS).
The test, created by scientists at the University of East Anglia and Oxford Biodynamics, identifies a unique DNA-folding pattern found only in ME/CFS patients.
In trials involving 47 patients and 61 healthy volunteers, the test showed 92% sensitivity and 98% specificity.
“This is a significant step forward,” said lead researcher Prof Dmitry Pshezhetskiy. “It could transform how we diagnose and manage this disease.”
The breakthrough could help end years of misdiagnoses and delayed treatment for patients dismissed as having “imaginary” symptoms.
However, some experts urged caution, saying larger, independent studies are needed before the test reaches clinics.
“This looks promising but must be validated,” said Dr Charles Shepherd of the ME Association. “We need to ensure it’s unique to ME/CFS.”
If confirmed, the £1,000 test could offer long-awaited clarity for millions living with this debilitating condition.
