Comparação da glicemia em cães utilizando o glicosímetro portátil e o método de referência laboratorial

Abstract

The increase or decrease in the glucose concentration in the blood is a common endocrine alteration in human beings and animals that can cause serious consequences to their health condition. Dosing the glucose of patient with hypo or hyperglycemia allows the same ones to receive appropriate treatment, propitiating a better life quality. The present work had as object to determine the glycemic values of dogs using a portable glucometer (Accu-Chek® Advantage / Roche) projected for human patients, and to compare the results obtained with that equipment to those acquired with the enzymatic-colorimeter (GOD-POD) according to Trinder laboratorial method, since it is considered a standard technique. Once proving that exists a good correlation among the results obtained with the two methods, it becomes possible for the Veterinary Doctors to use the glucometer in their routine with the intention of diagnosing alteration in their patients' glycemia and nevertheless, obtain important information that will help to govern the therapeutic conducts in animals with diseases such as Diabetes mellitus. Another purpose of this work was to describe which factors can alter the precision of the results obtained with the portable glucometer. For the development of the research 53 animals of the canine species, of varied age, sex, weight and breed, assisted at the Veterinary Hospital of the Department of Veterinary Medicine (DMV) of the Rural Federal University of Pernambuco (UFRPE) were used). In 17 patients it was observed factors of risks that could alter the precision of the results in the glucometer, such as low hematocrit, inadequate soak of the test strip, a part of the sample was over the reagent strip or still, the accomplishment of the test passed the 15 seconds recommended by the manufacturer of the equipment, and as consequence, only 36 animals were considered eligible for the study of the evaluation of the portable glucometer in relation to the laboratorial method. It was concluded that the glucose dosage in dogs using the portable glucometer Accu-Chek® Advantage can be considered clinically useful, because the differences obtained among the methods are inside of the margin established by the regulators entities of the area.
