OBJECTIVES: The aim of the study was to evaluate whether a hand-held @entity1011 analyser (StatSensor Xpress; @entity36738 ), available for @entity1 @entity1 , can be used to measure @entity1011 reliably in @entity468 . METHODS: Analytical performance was evaluated by determining within- and between-run coefficient of variation (CV, %), total error observed (TEobs, %) and sigma metrics. Fifty client-owned @entity468 presenting for investigation of clinical disease had @entity1011 measured simultaneously, using @entity36738 (whole blood and plasma) and a reference instrument (Konelab, serum); 48 paired samples were included in the study. @entity1011 correlation between methodologies ( @entity36738 vs Konelab) and sample types (SSXpwhole blood vs SSXpplasma) was assessed by Spearman's correlation coefficient and agreement was determined using Bland-Altman difference plots. Each @entity1011 value was assigned an IRIS stage (1-4); correlation and agreement between Konelab and @entity36738 IRIS stages was evaluated. RESULTS: Within-run CV (4.23-8.85%), between-run CV (8.95-11.72%), TEobs (22.15-34.92%) and sigma metrics (   3) did not meet desired analytical requirements. Correlation between sample types was high (SSXpwhole blood vs SSXpplasma; r = 0.89) and between instruments was high (SSXpwhole blood vs Konelabserum; r = 0.85) to very high (SSXpplasma vs Konelabserum; r = 0.91). Konelab and SSXpwhole blood IRIS scores exhibited high correlation (r = 0.76). Packed cell volume did not significantly affect @entity36738 determination of @entity1011 . Bland-Altman difference plots identified a positive bias for the @entity36738 (7.13  mol/l SSXpwhole blood; 20.23  mol/l SSXpplasma) compared with the Konelab. Outliers (1/48 whole blood; 2/48 plasma) occurred exclusively at very high @entity1011 concentrations. The @entity36738 failed to identify 2/21 azotaemic @entity468 . CONCLUSIONS AND RELEVANCE: Analytical performance of the @entity36738 in feline @entity1 is not considered acceptable. The @entity36738 exhibited a high to very high correlation compared with the reference methodology but the two instruments cannot be used interchangeably. Improvements in the @entity36738 analytical performance are needed before its use can be recommended in feline clinical practice.
