Blood tests may help detect who is likely to get long Covid: Study

A blood test taken at the time of Covid-19 infection can help determine whether a person is likely to develop long-term Covid, according to new research.

The study, published in the Lancet eBioMedicine journal, analysed proteins in the blood of healthcare workers infected with SARS-CoV-2 and compared them to samples collected from healthcare workers who had not been infected.
