Clinical Significance
Creatinine is eliminated by glomerular filtration. Creatinine is used to monitor acute and chronic renal disease, estimate glomerular filtration, and to assess the status of renal patients. Urine creatinine is used to calculate creatinine clearance, measure 24-hour urine collections, and serves as a reference quantity for other analytes. Creatinine levels may also play a role in the administration/dosage of certain medications, i.e. aminoglycosides and digoxin.
