Research carried out at Imperial College London, UK, suggests that long Covid could soon be diagnosed by a simple blood test.
Pilot data has identified autoantibodies in the blood of long Covid patients. These autoantibodies were not found in the blood of people who recovered quickly from the virus or had never tested positive for the disease.
Unlike regular antibodies that help to fight off infections, autoantibodies mistakenly target and react with a person’s own tissues and organs. They have been linked to a number of autoimmune conditions, such as Grave’s disease, arthritis and some cases of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).
