Figure 3: Receiver operating characteristic curve analysis of carbamylated hemoglobin. Receiver Operating Characteristic curve analysis done to study the utility of carbamylated hemoglobin in the differentiation of acute from chronic kidney disease showed significant area under curve (AUC=0.840, 95% CI=0.690-0.936, p<0.0001). A cut-off value of 98.33 μgVH/g Hb was obtained with the best combination of 85% sensitivity and 75% specificity to differentiate AKI from CKD
