Analytical Validation of a New Enzymatic and Automatable Method for d-Xylose Measurement in Human Urine Samples

Figure 3

Concordance of the enzymatic assay versus the phloroglucinol method. The concordance between both methods was studied using the ROC curves of the enzymatic assay generated taking as reference the results of the phloroglucinol reaction. ROC curves were represented before and after correcting the discrepancies of patients 6 and 8.
