In comparison to the COVID-19 patients, the IA patients had lower levels of lymphocyte count, lymphocyte percentage, neutrophil-to-lymphocyte ratio (NLR), haemoglobin (n = 59), and albumin (n = 61) but higher levels of neutrophil count, neutrophil percentage (n = 59), activated partial thromboplastin time (APTT), prothrombin time (PT) (n = 51), C-reactive protein(n = 61), and procalcitonin (n = 44). Here, ALB is linked to COVID-19.
