What Are Normal Urine Creatinine Levels?
For men, normal urine creatinine levels fall between 0.8 and 1.8 grams per day, according to the University of Rochester Medical Center. For women, the values fall between 0.6 and 1.6 grams per day. Urine creatinine levels may fluctuate depending on race, muscle mass and certain medications.
Creatinine is a metabolic waste product of muscle metabolism and meat consumption, according to Mayo Clinic. The kidneys filter creatinine from the blood, and excrete it through the urine. Physicians may order a urine creatinine test to detect kidney malfunctioning, according to the American Association for Clinical Chemistry. Other indicators of kidney dysfunction include fatigue, swelling and hypertension.
