GPT and metabolic dysfunction-associated steatotic liver disease: Similarly our study showed that the serum values of AST, ALP and GGT are higher in cases with ALD, the serum values of ALT was slightly higher in cases of NAFLD than in ALD.5,16 Rise in these liver enzyme indicate the leakage of hepatic intracellular enzyme into circulation indicating to be a marker for hepatocellular damage.17 Transaminase levels in ALD patients were AST dominant while those in NAFLD patients were ALT dominant.5 Our studies show a markedly higher value of GGT in cases with ALD.
