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

Updated:1 year, 1 month ago

New Delhi, Sept 29 (ANI): 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. Usually, protein levels in the body are stable. But the researchers found a dramatic difference in levels of some of the proteins up to six weeks following infection, suggesting disruption to a number of important biological processes. Using an artificial intelligence (AI) algorithm, they identified a "signature" in the abundance of different proteins that successfully predicted whether or not the person would go on to report persistent symptoms a year after infection. The researchers say that if these findings are repeated in a larger, independent group of patients, a test could potentially be offered alongside a polymerase chain reaction (PCR) test that could predict people's likelihood of developing long Covid.
