Long Covid continues to evade a clear diagnostic test, researchers reported in a study published Monday in the Annals of Internal Medicine. They found no differences between those with long Covid and those without the condition. Different symptoms were assigned different scores, and a long Covid diagnosis was met if the score reached a level of 12. There was no time cutoff for symptoms and a positive Covid test was not required for diagnosis. Dr. Nisha Viswanathan, the director of the long Covid clinic at UCLA Health, was not surprised with the results based on her experience working with long Covid patients for three years.
