Best data I know of is Remer T et al 2002 "Anthropometry based reference values for 24h urine creatinine excretion during growth and their use in paediatric and nutritional research" Am J Clin Nutr 75: 561-9.

Dear Mailbase,
We are seeing a number of paediatric patients with creatinine results slightly above our reference interval but with no renal concerns on further investigation. We are using the Roche Jaffe assay and reporting Roche reference intervals.
I would be interested to know whether any other labs are also seeing slightly raised creatinine results in paediatrics and with which creatinine method/reference intervals.
In addition, are there any other labs using the Roche Jaffe creatinine assay but quoting paediatric reference intervals from another source?
Many thanks,
Naomi
