Ferritin correlates with AST and is increased in patients with impaired liver function. (A) Ferritin and AST levels correlate in all hospitalized patients. (B) Ferritin levels correlate with AST concentration in non ICU and ICU patients. Displayed are ferritin concentrations in patients with normal AST and elevated AST in (C) non ICU and (D) ICU patients. Data are shown as mean ± SEM, n: (C-D). *p<0.05; **p<0.01; ***p<0.001 according to Spearman correlation or Student's t-test. AST, aspartate aminotransferase; ICU, intensive care unit.
