Serum concentrations of canine interleukin-1 receptor antagonist protein in healthy dogs after incubation using an autologous serum processing system. Academic Article uri icon


  • The objectives of this study were to optimize and validate a canine IL-1RA ELISA using commercially available reagents and to determine the effect of an autologous serum processing system (IRAP II) on IL-1RA concentrations in canine serum. The clinical detection limit of the optimized ELISA was 188.8 to 39,965.6 pg/mL. The observed-to-expected ratio (O:E) for three serial dilutions for four serum samples ranged from 109.6 to 132.2%. The O:E for four serum samples spiked with four concentrations of canine IL-1 RA ranged from 98.7 to 114.3%. Coefficients of variances for intra- and interassay variability ranged from 1.4 to 3.0 and 6.3 to 9.8, respectively. The ELISA was sensitive, linear, accurate, precise, and reproducible. MeanSD serum concentration of IL-1RA in 12 healthy dogs was 396.6208.0 pg/mL. There was a significant increase in IL-1RA when blood was incubated in the IRAP II system (15,955.06421.0 pg/mL, P<0.0001).
