A world-first blood test which has the potential to revolutionise the diagnosis and treatment of people with chronic pain is being revealed at a conference in Sydney today.
The test developed by neuroscientist Mark Hutchinson identifies the intensity of chronic pain by colour bio-markers.
Professor Hutchinson says it'll mean better diagnosing of pain in babies and people with dementia, who can't communicate the extent or source of the pain.
The test could be ready for use by GPs within 18 months.
About one in five people suffer from chronic pain.
