In this program participants will learn about current diagnostics for acute and chronic kidney disease in dogs and cats. Participants will review IRIS staging of both acute kidney injury and chronic kidney disease and how to use these guidelines to target therapy. Discussion will include conventional testing for renal function and focus on renal biomarkers and emerging tests for earlier detection of kidney disease and associated problems including RenalTech, urinary Cystatin B and Fibroblast Growth Factor-23 (FGF-23). This program will also briefly discuss management strategies including dietary intervention, phosphorus restriction and binders, and treatment of secondary issues. Lastly, discussion will include supportive care measurements, particularly for patients with chronic kidney disease, and available evidence for these treatments.
