Relationship of glomerular filtration rate based on serum iodixanol clearance to IRIS staging in cats with chronic kidney disease.

The article presents a study which examines the correlation between glomerular filtration rate (GFR) estimated from an equation based on the serum iodixanol clearance technique and International Renal Interest Society (IRIS) stages of chronic kidney disease (CKD) in cats. Serum iodixanol concentration was measured by reversed-phase high-performance liquid chromatography. The percent changes in the basal GFR values calculated from the equation in CKD cats are the same with IRIS stages 1-3.
