                Frequently Asked QuestionsLaboratory Evaluation of Kidney Disease
Laboratory measurement and reporting are critical to promoting early detection and management of chronic kidney disease (CKD). NIDDK's major laboratory-related efforts address GFR and urine albumin.
    Glomerular Filtration Rate (GFR)
    NIDDK encourages routine reporting of estimated GFR with all serum creatinine determinations for patients age 18 and older, when appropriate and feasible. Learn more about estimating and reporting GFR.
