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.reatinine levels that reach 2.0 or more in babies and 10.0 or more in adults may indicate severe kidney impairment and the need for a dialysis machine to remove wastes from the blood.
Normal creatinine clearance for men is between 97 to 137 milliliters per minute, and women have a normal clearance of 88 to 128 milliliters per minute. BUN/creatinine is the ratio between blood urea nitrogen (BUN), a waste product in the blood from protein metabolism, and creatinine.ormal creatinine clearance for men is between 97 to 137 milliliters per minute, and women have a normal clearance of 88 to 128 milliliters per minute.
