Fasting blood glucose (FBG), liver and renal functions, and COVID-19 biomarkers (total leukocyte count (TLC), neutrophil and lymphocyte counts, and serum levels of C-reactive protein (CRP), D-dimer, ferritin, and lactate dehydrogenase (LDH)) were among the baseline laboratory tests [9,10] and [11] performed. Here, CRP is linked to COVID-19.
