ALB and COVID-19: A study on 12 cases (nine with mild, three with severe disease) showed that Ct values from respiratory samples were correlated with disease severity scores like acute respiratory distress syndrome (ARDS) index PaO2/FiO2 ratio and lung injury Murray score, as well with biochemical indicators like albumin levels and lymphocytes and neutrophils percentages, and concluded VLs could serve as a COVID-19 severity predictor [17].
