Reference Ranges for Serum Creatinine in Infants, Children and Adolescents

Abstract

Reference ranges for serum creatinine, derived from 2110 cases aged between 1 day and 20 years, are presented. Levels fall during the neonatal period and then increase with age in both sexes. Levels fall more rapidly in full term infants than in premature infants and are significantly higher in males than in females aged 15 years and above.
