In addition, we found that plasma creatinine, PUN, cystatin C, myoglobin, NT-proBNP, direct bilirubin, prothrombin international normalized ratio (PT-INR), D-dimer, FDP, and nucleated red blood count/percentage were higher and eGFR, albumin-globulin ratio (AGR), haematocrit, SpO2, TCO2, partial pressure of carbon dioxide, ABR, base excess in the extracellular fluid, plasma carbon dioxide (PCO2), apolipoprotein, and PTA were lower in COVID-19 patients. This evidence concerns the gene MB and COVID-19.
