Q: What is the normal value of 24 hour urine creatinine for 2 and half year female child? My child 24 hour urine creatinine value is 760 milligrams/day. Is it OK.

A:Normal creatinine excretion in urine ranges from 15 to 25 ml/kg/day and varies with gender. In other words, it is approx. 15-20 ml/kg/day for females. Since, you have not provided the weight of your daughter I can not comment on whether her creatinine excretion is normal or not. However, you can do the maths yourself. I must submit that kidney function assessment based on 24 hour urine collection may be subject to errors. It has to be ensured that urine collection was done for exact 24 hours, stored under refrigerated conditions and processed immediately.
