Measurement of uACR and cystatin C in addition to CKDEPI eGFR reduced those classified as having potential moderate CKD (KDIGO categories G3a and 3b) to 230 (estimated prevalence 4%, Table 2).[3] Fig. 2 summarises the effect of the use of the different measures on the risk profile and estimated prevalence of CKD among those tested for all three biomarkers (n = 5260). Here, CST3 is linked to chronic kidney disease.
