ALB and COVID-19: Using the continued admitted patients diagnosed with COVID-19 prospectively, we have suggested that neutrophil percentages > 70%, neutrophil counts > 6.3 × 109/L, lymphocyte percentages < 20%, NPR > 2.3, NLR > 3.9, albumin < 40 g/L, and LDH > 245 U/L were risk factors for illness severity in COVID-19 patients.
