Este estudo avaliou o efeito do HT sobre o desempenho de dois GT veterinários para uso em cães em comparação a dois métodos laboratoriais de referência: glicose hexoquinase (Hx) e glicose oxidase (GOx). Ambos os GT apresentaram boa performance em amostras com HT inferior à 37%: GT1 r=0,90 com MLab Hx e r=0,94para GOx. Por sua vez, GT2 apresentou r=0,84 tanto para Hx quanto para GOx. Entretanto, apenas GT1 demonstrou desempenho adequado em amostras com HT (entre 37% e 55% (r=0,90 para Hx) e nenhum GT ofereceu atuação apropriada em amostras com HT superior à 55%. Conclui-se que o resultado apresentado por ambos GT altera de acordo com o hematócrito do animal. Deve-se considerar que pacientes com disglicemias estão frequentemente expostos às alterações clínico-patológicas, e a adoção destes GT específicos como estratégia de monitoramento pode não ser adequada, por isso a importância de outros procedimentos de medição da glicose serem empregados.Glucometers (GT) are widely used as tools for monitoring blood glucose in dogs and hematocrit (HT) is one of the factors that can change its accuracy, possibly due to the change in blood viscosity, preventing the reaction with plasma on the surface of the strip, alteration of the diffusion kinetics and / or modification of the plasma volume, resulting in insufficient plasma volume for the GT test. This study evaluated the effect of HT on the performance of two veterinary GT for use in dogs compared to two reference laboratory methods (MLab): glucose hexokinase (Hx) and glucose oxidase (GOx). Both GT showed good performance in samples with HT below 37%: GT1 r = 0.90 with MLab Hx and r = 0.94 for GOx. In turn, GT2 presented r = 0.84 for both Hx and GOx. However, only GT1 demonstrated adequate performance in samples with HT between 37% and 55% (r = 0.90 for Hx) and no GT offered adequate performance in samples with HT greater than 55%. It can be concluded that the result presented by both GT changes according to the animal's hematocrit. It should be considered that patients with dysglycemias are frequently exposed to clinical-pathological changes, and the adoption of these specific GT as a monitoring strategy may not be adequate, so the importance of other procedures glucose measurement devices are employed.porUniversidade Federal de Minas GeraisUFMGBrasilVET - DEPARTAMENTO DE CLÍNICA E CIRURGIAArs VeterinariaCãesGlicemiaGlicemia - mediçãoCãesGlicemiaMonitoramentoInterferência do hematócrito sobre o desempenho de dois glicosímetros veterinários em cãesInterference of haematocrit in the performance of two veterinary glucometers in dogsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.arsveterinaria.org.br/index.php/ars/article/view/1265Fernanda Morcatti CouraMaria Correa LopesFabiola de Oliveira Paes LemeAdriane Pimenta da Costa-Valinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/67436/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALInterferência do hematócrito sobre o desempenho de dois glicosímetros veterinários em cães.pdfInterferência do hematócrito sobre o desempenho de dois glicosímetros veterinários em cães.pdfapplication/pdf80264https://repositorio.ufmg.br/bitstream/1843/67436/2/Interfer%c3%aancia%20do%20hemat%c3%b3crito%20sobre%20o%20desempenho%20de%20dois%20glicos%c3%admetros%20veterin%c3%a1rios%20em%20c%c3%a3es.pdf7c0f886a2105d5f9f3bf6fe5430b3a5aMD521843/674362024-04-18 17:37:56.76oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2024-04-18T20:37:56Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
