Comparison of five tuna plasma analytes measured on two automated blood analyzers

Abstract

Plasma biochemistry parameters of 32 bluefin tuna were analyzed on two blood analyzer systems, VetTest 8008 and Olympus AU2700, and the results compared and correlated. Statistically significant differences (p<0.0001) between the two analyzers were found for the total cholesterol, triglyceride, and aspartate aminotransferase analytes, but not for those of glucose and total proteins, which demonstrated almost identical values and ranges on both analyzers (p = 0.383 and 0.188, respectively). The coefficients of variation were high for most parameters on both analyzers. Overall, we conclude that data obtained with both analyzers have the same clinical significance. In routine investigations on tuna blood, due to the relatively small numbers of available samples and small sample volumes, it is more likely that the bench-top dry-slide analyzer (VetTest 8008) will be the preferred analytical system to a high-volume primary analyzer (Olympus AU2700).
