Scientists develop first ‘accurate blood test’ to detect chronic fatigue syndrome
Scientists have made a breakthrough by developing the first accurate blood test for diagnosing myalgic encephalomyelitis, commonly known as chronic fatigue syndrome (ME/CFS). This is significant because currently, there is no definitive test for the condition, leading to many patients being misdiagnosed or undiagnosed for years. While this advancement offers hope for ME patients, experts caution that further studies are necessary to validate the test's effectiveness.
