Abstract: Objective To investigate the currently-used biochemical thresholds related to the diagnosis of drug-induced liver injury (DILI) in order to provide reference for monitoring of adverse drug reactions. Methods Based on the newly released guidelines for clinical diagnosis and treatment, expert consensus and health industry standards of DILI at home and abroad, the latest classification of pathogenesis of DILI and the establishment of thresholds of biochemical indicators related to diagnosis were summarized. Results The current international biochemical diagnostic criteria for DILI were determined as follows: ①ALT≥5×ULN; ②ALT≥3×ULN, TBL > 2×ULN, without ALP elevation; ③ALP≥2×ULN, especially with 5'- nucleotide enzyme elevation, but without any bone disease (ALP elevation is caused by the liver). The reference intervals of biochemical test indexes related to the diagnosis of DILI were age-dependent in children. Conclusion In DILI-related studies, especially those for children, the thresholds of DILI-related biochemical indicators should be determined by the reference interval corresponding to each age group in order to make outcome judgment more accurate.
