New Delhi, Oct 2 (ANI): According to research, a blood test conducted at the time of Covid-19 infection can help indicate whether a person is likely to develop long-term COVID. 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.
