In women  88-128 mL/min. and 97 to 137 mL/min. in males.
As blood flows through the kidneys, creatinine is excreted out into your urine along with other waste products. Levels of creatinine in the urine taken over 24 hours, together with blood levels of creatinine, can be used to estimate the rate at which your kidneys do their filtering job. Determining the level of creatinine in your urine can help your doctor determine whether or not your kidneys are functioning well. Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dL) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females. 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. Results. Creatinine and creatinine clearance tests measure creatinine levels in your blood and urine to give information about how well your kidneys are working. The creatinine clearance value is found from the amounts of creatinine in the urine and blood and from the amount of urine you pass in 24 hours. The creatinine levels in both urine and blood are determined and compared. Normal creatinine clearance for healthy women is 88-128 mL/min. and 97 to 137 mL/min. in males (normal levels may vary slightly between labs). Blood urea nitrogen (BUN) level is another indicator of kidney function. Creatinine and creatinine clearance tests measure the level of the waste product creatinine in your blood and urine. These tests tell how well your kidneys are working. The substance creatine is formed when food is changed into energy through a process called metabolism. Results.
