ALB and susceptibility to pneumonia measurement: It was reported in some previous studies that hypoalbuminemia, lymphopenia, decreased lymphocyte and neutrophil percentages, high C-reactive protein levels and high lactate dehydrogenase (LDH) levels were common laboratory abnormalities.11,12,13,14 It was also found that serum albumin values, lymphocyte cell counts and percentages, neutrophil percentages and LDH and CRP levels were highly correlated with acute lung damage.8,9 These conditions can play critical roles in cases of severe pneumonia that develop due to COVID-19.
