GPT and COVID-19: However, ALT results of COVID-19 patients (median 14.00 U/L, IQR 11.00-25.00 U/L) was lower than that in NV group (median 18.00 U/L, IQR 13.00-28.00 U/L), and the AST results of COVID-19 patients (median 31.20 U/L, IQR 21.00-40.28 U/L) was lower than that in NCV (median 36.00 U/L, IQR 30.00-46.00 U/L) and NV group (median 35.00 U/L, IQR 29.00-43.00 U/L) (Table 2).
