Scientists say they have detected irregularities in the blood of long Covid patients that could one day pave the way for a test for the condition.
Imperial College London researchers found a pattern of rogue antibodies in the blood of a small number of people with long Covid.
They hope it could lead to a simple blood test within six to 18 months.
Dr Elaine Maxwell, from the National Institute of Health Research, said the early findings were "exciting".
She said there could be "a number of different things happening after a Covid-19 infection" and an autoimmune response "has been one of the suspected mechanisms".
But she warned that long Covid was a "complex condition", saying it was important to continue to research the other causal factors so all different types of post-Covid syndrome could be diagnosed and treated.
Long Covid is not yet fully understood and can cover a range of symptoms lasting long after initial infection including fatigue, breathlessness, headaches and muscle pain.
There are currently no tests to diagnose long Covid.
