what is the u creatinine random
Confidence votes 302. Normal random urine creatinine levels range from 40 to 300 mg/dl but it should be kept in mind that this range is somewhat dependent on the individual's sex, age and if there are other mitigating factors. The range is typically adjusted based on a few outside factors, but 40 to 300 is a pretty good all-purpose range for URINE, not serum.
