Objective: This study aimed to validate the analytical precision of the Accutrend® Plus portable electronic equipment (PE) to determine glucose (GLU), total cholesterol (TC), and triglycerides (TG) in rats and dogs using the conventional laboratory method (CM) as a reference.
Materials and Methods: To determine the analytical accuracy of the Accutrend® Plus in the mea¬surement of GLU, CT, and TG. The EP-9-A2 guide (Clinical and Laboratory Standards Institute), Bland-Altman graphical analysis, and Lin’s correlation coefficient of concordance (CCC) were implemented.
Results: The average differences (p > 0.05) between PE and CM for GLU, TC, and TG were 2.21, 1.20, and 0.72 mg·dl−1, respectively, in rats and 1.06, 4.30, and 2.41 mg·dl−1, respectively, in dogs (p > 0.05). Both methods showed a linear relationship with Pearson’s correlation coefficients > 0.96 and R2 > 0.97 for the three biochemical indicators evaluated in both species. The GLU, TC, and TG values obtained by the PE were substantial, as evident from Lin’s CCC > 0.96.
Conclusion: The PE Accutrend® Plus is potent for monitoring GLU, TC, and TG in rats and dogs because of its precision and ability to facilitate measurement by reducing stress in animals during sampling.
