The range for a normal test result depends on your age and gender. For adults younger than 40, normal levels are typically in the range of: 107 to 139 mL/min or 1.78 to 2.32 mL/s (SI units) for men. 87 to 107 mL/min or 1.45 to 1.78 mL/s (SI units) for women. Creatinine clearance rates go down as you age.For every decade after age 40, a normal test result is 6.5 mL/min less than the numbers above. For newborns, the normal range is 40 to 65 mL/min. An abnormal creatinine clearance rate may mean you have a problem with your kidneys.Or it may mean a problem somewhere else in your body is affecting blood flow to the kidneys.ealthy kidneys remove creatinine from the blood. It then passes out of your body through urine. The creatinine clearance test usually compares the creatinine level in a 24-hour urine sample with the creatinine level in your blood. This tells your doctor how well your kidneys are working.
