• Multiple New Loci Associated with Kidney Function and Chronic Kidney Disease: The CKDGen consortium (2010, neutral): “To account for between-laboratory variation across studies, serum creatinine was calibrated to the National Health and Nutrition Examination Study (NHANES) standards in all studies (including replication cohorts) as described previousl”
• Multiple Novel Loci are Associated with Indices of Renal Function and Chronic Kidney Disease (2009, methodology): “To be comparable across studies, creatinine values in all studies were calibrated using regression to age- and sex-adjusted mean values from a nationally representative US survey as described previousl”
• Level of kidney function as a risk factor for atherosclerotic cardiovascular outcomes in the community. (2003, result): “Because both NHANES III and ARIC were designed as representative samples of the population, and NHANES III data have been directly compared with the MDRD samples (11), it was assumed that the mean serum creatinine for a given age, gender, and race should be comparable in the two studies.”

• The Metabolic Syndrome and Chronic Kidney Disease in U.S. Adults (2004, methodology): “Serum creatinine level was calibrated for measurement variance between NHANES III and MDRD clinical laboratories (18).”
• Recommendations for improving serum creatinine measurement: a report from the Laboratory Working Group of the National Kidney Disease Education Program. (2006, background): “This calibration error is relatively greater and contributes to larger uncertainty in GFR estimates at lower creatinine values near the upper limit of the reference interval (20) .”
• Performance of the modification of diet in renal disease and Cockcroft-Gault equations in the estimation of GFR in health and in chronic kidney disease. (2005, methodology): “(14), this illustrates that calibration errors can greatly distort the interpretation of creatinine-based equations in the normal range of SCr.”
• Chronic kidney disease awareness, prevalence, and trends among U.S. adults, 1999 to 2000. (2004, methodology): “To minimize the impact of these limitations, we used a newly developed equation with increased precision of estimating GFR and calibrated the serum creatinine measurements to the laboratory that generated the data for development of this equation (19).”
• National Kidney Foundation Practice Guidelines for Chronic Kidney Disease: Evaluation, Classification, and Stratification (2003, background): “Differences among clinical laboratories in calibration of serum creatinine assays can account for errors in GFR estimates as high as 20%, which are especially important in individuals with near-normal serum creatinine concentration (39, 40 ).”
