We offer to report urine calcium:creatinine ratio in kids as the
sample
tends to be easier to collect.
Reference range = 0.06 to 0.74 mmol/mmol creat
I can't remember where this came from so don't tell CPA
Not enough data to draw proper correlations. Perhaps a colleague would
like
to run a trial on 24hr samples received.
with best wishes

Subject: Urinary calcium and phosphate reference ranges
Dear Lab Community,
While (varying !) Ca and P reference ranges are available for 24 h
urine
samples, it is difficult for me to find numbers for random urine
samples.
I know that 24 h urine samples should be preferred. However, please
remember that it is no easy task to collect a 24 h urine from a 2
year-old boy ...
As always, your collected wisdom is welcome.
Thank you for your input.
