WebDec 22, 2016 · Using the CKD-EPI equations, this range of non-different serum creatinine values is converted to eGFR values that may vary between 58 and 92 mL/min/1.73 m 2 for Jaffe serum creatinine and between 61 and 84 mL/min/1.73 m 2 for the enzymatic assay results. The intrinsic variability of creatinine is thus not so negligible when it is used in … WebCreatinine clearance ( CrCl) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus). The additional proximal tubule secretion falsely elevates the CrCl estimate of GFR. 12
WebIDMS-traceable creatinine values are 10-20% lower than values generated by non-IDMS calibrated methods. This decreased creatinine value leads to a falsely elevated glomerular filtration rate (GFR) and creatinine clearance (CrCl) when the value is plugged into traditional estimating equations or used in calculations. ... and the 10-20% ... WebThe bias observed in urine creatinine was 1.31 (E) and −0.81 (E-IDMS) compared with J, which is small given the large range of urine creatinine from 3 to 273 mg/dL.
WebJan 1, 2006 · An LC-IDMS method has been developed for serum creatinine and nominated in the JCTLM cycle II for consideration as a reference measurement procedure . LC-IDMS methods have much simpler and faster sample preparation than do GC-IDMS methods and would be much more amenable to split-sample comparisons on a more … WebeGFR (estimated glomerular filtration rate) = mL/min/1.73 m 2 S cr (standardized serum creatinine) = mg/dL age = years Assays Creatinine is assayed using methods that are traceable to IDMS assigned NIST certified reference materials.

WebThe revised Schwartz formula 1 is: Height is measured in cm. Serum creatinine is measured in mg/dL. Measured creatinine should be in steady state. This formula may be most accurate in the range of 15 to 75 mL/min per 1.73 m 2. Values >75 should be reported as such rather than as a specific number.
