Plasma creatinine Plasma creatinine

Cat Normal range: 40-130 mmol/l

Unlike BUN, plasma creatinine concentrations are unaffected by other systemic factors and because it is exclusively excreted via the kidneys high concentrations indicate reduced renal function whatever the primary cause. Creatinine is therefore a more useful test for renal function than BUN.
