photometric

1-2 days

Remark

SDMA is formed during protein degradation, is excreted exclusively via the kidneys and is helpful for the early detection of renal dysfunction, even in the creatinine-blind area. 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. An elevated SDMA level can already indicate a 30% reduction in glomerular filtration rate (GFR).
