LI Unit 1, Case 1 (Lucy) How to Check for Kidney Function/Failure Serum Analysis The standard indicators of renal function are serum levels of urea nitrogen and creatinine ; their ratio (BUN:Creatinine) is normally about 10:1. The most reliable single indicator of glomerular function is the serum level of creatinine. The endogenous creatinine clearance in milliliters per minute estimates the glomerular filtration rate (GFR). A 24 hr urine collection is usually obtained; however, in small children from whom collection is difficult, a 12-hr daytime specimen is acceptable. Total daily creatinine excretion (creatinine index) should be 14-20 mg/kg. Creatinine indices on either side of this range suggest collections that were either inadequate or excessive. A reliable formula for quick approximation of creatinine clearance is based on plasma creatinine level and length in cm. C cr (mL/min/1.73m 2 ) = 0.55x height (in cm)/P cr in mg/dL C cr = creatinine clearance P cr = plasma creatinine level
