The normal range for serum creatinine (in the blood) is usually between 0.6 and 1.3 milligrams per deciliter (mg/dL) although it varies between labs, between men and women, and by age.
Creatinine levels tend to be higher in men and people with large muscles. Measuring creatinine is only the first step to finding your level of kidney function. The normal serum creatinine range for men is 0.5-1.5 mg/dL.
