Urine
The kidney develops rapidly over the first year of life. Its handling of many filtered compounds is substantially different, for example:
Urine Birth-2.4 mmol/mmol calcium 6 months Creatinine
6-12 months 0.09-2.2 mmol/mmol Creatinine
1-3 years 0.06-1.4 mmol/mmol Creatinine
3-5 years 0.05-1.1 mmol/mmol Creatinine
7 years 0.04-0.07 mmol/mmol to adult Creatinine
Urine 7-12 months 1.2-19 mmol/mmol phosphate Creatinine
1-3 years 1.2-12 mmol/mmol Creatinine
3-6 years 1.2-8 mmol/mmol Creatinine
Adult 0.8-2.7 mmol/mmol Creatinine
CSF
Protein 1 month 0.26-1.2 g/L 1-3 months 0.1-0.8 g/L 3 months 0.1-0.5 g/L
