Figure Lengend Snippet: Method comparison between a kinetic alkaline picrate assay (Abbott Architect c16000 analyser) and the LC-MS/MS assay using 20 anonymised surplus serum samples. (A) Deming regression analysis of LC-MS/MS creatinine plotted against the Abbott Jaffe creatinine result. (B) Bland Altman (difference) plot illustrating the agreement between the two methods. Average bias and 95% limits of agreement are shown.

Article Snippet: The percentage change in measured creatinine compared to the unspiked sample was calculated for both creatinine methods. (B) Fifteen patient samples with high concentrations of endogenous glucose were analysed for creatinine by both assays and the % difference between the Abbott Jaffe method and the LC-MS/MS assay is shown for each sample.

Figure Lengend Snippet: Effect of glucose on measured creatinine. (A) Pooled serum was spiked with glucose to provide a range of concentrations. Glucose was measured using a hexokinase enzymatic assay and creatinine was analysed using both the Abbott Architect Jaffe method and by LC-MS/MS. The percentage change in measured creatinine compared to the unspiked sample was calculated for both creatinine methods. (B) Fifteen patient samples with high concentrations of endogenous glucose were analysed for creatinine by both assays and the % difference between the Abbott Jaffe method and the LC-MS/MS assay is shown for each sample.

Figure Lengend Snippet: Effect of bilirubin on measured creatinine. Five serum samples were spiked with bilirubin in DMSO or with DMSO alone, and the bilirubin concentration and icteric index were measured on an Abbott Architect analyser. Abbott Jaffe creatinine and LC-MS/MS creatinine values are plotted against icteric index (A, C) or measured bilirubin (B, D).
