Modeling the variability of creatinine measurements improves estimates of the glomerular filtration rate

Background: The precision of the formulae used to estimate glomerular filtration rate (GFR) decreases when the serum creatinine (SCr) assay is biased compared with the assay used during the development of the formulae.

Methods: For 100 children referred for ⁵¹Cr-EDTA clearance (CL_EDTA), SCr was measured with a JAFFE (classic Jaffe colorimetric creatinine assay), a compensated Jaffe (COMP), an enzymatic (ENZ) and an HPLC assay...
