SDMA is formed during protein degradation, is excreted by the kidneys and is used in laboratory diagnosis for the early detection of renal dysfunction (= GFR still > 30 %), even in the creatinine-blind range. In cats, a significant inverse correlation between the glomerular filtration rate and SDMA has been described. Determining the SDMA concentration is recommended if an early stage of renal dysfunction is suspected, e.g. because of beginning polyuria/polydipsia.
