Abstract

The purpose of this literature review is to describe laboratory tests routinely used in the small animal clinic for the detection of chronic kidney disease in felines, emphasizing the early diagnosis of this condition using a new laboratory tool for symmetrical dimethylarginine (SDMA). Chronic Kidney Disease (CKD) is characterized by the progressive and irreversible loss of the nephrons, which is the most basic function of the kidneys, correlated with the glomerular filtration rate (GFR) and the functional renal mass, respectively. Although the measurement of TF glomerular filtration rate is a reference method for the evaluation of renal function, its infrequent use allows the use of alternative markers such as serum urea and creatinine concentration. SDMA is a stable molecule, being widely excreted by the kidney, which makes it a good candidate for renal biomarker because its size and load allow it to be freely excreted by glomerular filtration. The SDMA dosage is extremely accurate, with the early diagnosis of CKD being currently possible, thus allowing for renoprotective interventions that delay its progress or aim to stabilize the disease.
