LONDON – With COVID-19 infection varying in severity from asymptomatic to lethal the search is now underway for biomarkers to predict which patients are most at risk of suffering severe disease. As one possibility, Menarini Silicon Biosystems (MSB) is using its Cellsearch liquid biopsy technology to capture and count circulating endothelial cells. Meanwhile, Oxford Biodynamics plc is applying its Episwitch platform to find prognostic and predictive epigenetic markers.
