Creatinine level
Creatinine is a metabolic product found in the body. It is a natural by-product of the breakdown of creatine and is excreted in the urine. The creatinine levels in the body depend on various factors. For more information, see What is creatinine?
Creatinine is an easy-to-determine marker for evaluating renal filtration. It can be measured in the blood or urine. The following creatinine levels are considered to be within the normal range:
Creatinine in blood serum
Men: 0.7–1.2 mg/dL (62–106 micromol/L)
Women: 0.5–0.9 mg/dL (44–80 micromol/L)
Creatinine in urine (24h collection)
Men: 1.00–2.40 g/d
Women: 0.70–1.60 g/d
There are different potential causes for altered or elevated creatinine levels. If in doubt, please consult your doctor.
