New pediatric percentiles of liver enzyme serum levels (alanine aminotransferase, aspartate aminotransferase, γ‐glutamyltransferase): Effects of age, sex, body mass index, and pubertal stage

Abstract

Current reference values of ALT, AST, and GGT serum levels were calculated for children between 11 months and 16.0 years, using modern analytical and statistical methods. This study extends the current knowledge about transaminases by revealing influences of age, sex, BMI, and puberty on serum concentrations of all three parameters and has for these parameters one of the largest sample sizes published so far.
