According to the 2019 Chinese Guidelines for the Diagnosis and Treatment of Anti-tuberculosis Drug-Induced Liver Injury [26], the diagnostic criteria for anti-tuberculosis drug-induced liver injury are as follows: after the use of anti-tuberculosis drugs, serum ALT no less than three times the upper limit of normal (ULN) and/or total bilirubin (TBIL) no less than two times the ULN; simultaneous increase in aspartate aminotransferase (AST), ALP, and TBIL, with at least one of them being no less than two times the ULN. Here, GPT is linked to tuberculosis.
