Drug toxicity (drug-induced nephrotoxicity) The symptoms of high creatinine can depend on the condition that’s causing it. Symptoms that can accompany high creatinine Your doctor will work with you to evaluate and interpret your results and what they may mean. It’s important that you don’t try to interpret your results on your own. Additionally, standard reference ranges can vary from lab to lab. A Note on reference ranges and ResultsĬreatinine levels may vary due to factors like by age, sex, race, hydration, or body mass. The amount of creatinine in the urine can also be used in conjunction with serum creatinine results to calculate your creatinine clearance, which measures how well your kidneys are filtering your blood. Urine creatinine levels above these ranges are considered high, and additional testing or repeat testing may be required. European units: 8.4 to 25.9 millimoles per 24 hours (mmol/day) for men 5.3 to 14.9 mmol/day for women.units: 955 to 2,936 milligrams per 24 hours (mg/day) for men 601 to 1,689 mg/24 hours for women A 24-hour urine sample involves collecting your urine over a period of 24 hours.Īccording to Mayo Clinic Laboratories, the normal urine creatinine ranges in a 24-hour urine sample are: Your doctor may collect a random (single) urine sample for this test, but they’ll more likely request a 24-hour sample.
Your doctor may want to confirm these values by using a urine test or by repeating the blood test. European units: 74.3 to 107 micromoles per liter (umol/L)Ĭreatinine levels above the normal range values may be considered high.units: 0.84 to 1.21 milligrams per deciliter (mg/dL) During this test, blood is collected from a vein in your arm and is then sent to a lab for further analysis.Īccording to Mayo Clinic, the normal range of creatinine (for an adult) in the blood is typically: You may also see this test referred to as a serum creatinine test. Creatinine levels can be determined using a blood test or a urine test.
