NASH subjects had significantly higher serum levels of liver enzymes [alanine transaminase (ALT) 68.7 ± 11 vs. 18.9 ± 2.6 IU/l; p = 0.0001], serum CK-18 M30 levels (544 ± 116 vs. 161 ± 9.8 IU/l; p = 0.0034) and ELF test (9.20 ± 0.3 vs. 7.34 ± 0.1; p < 0.001); values for all these parameters were within accepted reference ranges in the healthy volunteers. Here, GPT is linked to metabolic dysfunction-associated steatohepatitis.
