Laboratory Assessment of Diabetic Kidney Disease

IN BRIEF Regardless of etiology, chronic kidney disease (CKD) is identified by two laboratory tests: 1) estimated glomerular filtration rate (eGFR), a measure of kidney function, and 2) urine albumin-to-creatinine ratio (UACR), a measure of kidney damage. It is crucial for all health professionals to understand the significance and limitations of these tests to appropriately identify CKD patients, guide therapy, and determine prognosis. This article provides information that will enable diabetes educators and other clinicians to properly interpret eGFR and UACR laboratory results in the identification and management of CKD.
