Resumo: During a physical examination of cattle, it is often difficult to evaluate inflammatory processes, particularly in cases where the inflammation occurs in deeper regions. The glutaraldehyde test (GT), carried out using a sample of whole blood, allows the visual and semiquantitative identification of an inflammatory process in cattle. Considering that there are few biochemical tests that can be used in the field, the objective of this study was to verify the efficacy of the GT in detecting and predicting mild and severe inflammatory processes in bovine species, classified according to a physical examination, and in the presence of different diseases or lesions. The GT was used in conjunction with a physical examination in 176 cows over 12 months of age, with additional laboratory evaluations of packed cell volume, total protein, albumin, globulin, and fibrinogen. Using a cutoff point at 3 minutes of coagulation, the GT showed a sensitivity of 35.1%, specificity of 94.1%, positive predictive value of 74.1%, and negative predictive value of 75.2%. The GT correctly detected the most severe inflammatory processes under the field conditions of this study. The GT is a diagnostic aid that can be used as a fast and simple screening test during the physical examination of cattle.

O teste de glutaraldeído (TG), realizado com uma amostra de sangue total, possibilita a identificação visual e semiquantitativa de um processo inflamatório no bovino. Ao considerar que existem poucos testes bioquímicos passíveis de aplicação a campo, esse estudo objetivou verificar a eficácia do TG em detectar e predizer os processos inflamatórios leve e grave classificados conforme o exame físico e na presença de diferentes doenças ou lesões na espécie bovina. O TG foi aplicado juntamente com o exame físico em 176 fêmeas bovinas acima de 12 meses, além da avaliação laboratorial do volume globular, proteína total, albumina, globulina e fibrinogênio. O TG obteve sensibilidade de 35,1 %, especificidade de 94,1 %, valor preditivo positivo de 74,1 % e valor preditivo negativo de 74,2 % com o ponto de corte em 3 minutos de tempo de coagulação. O TG foi capaz de detectar corretamente os processos inflamatórios mais graves nas condições de campo deste estudo. O teste constitui um recurso de auxílio diagnóstico, podendo servir como triagem pela sua rapidez e facilidade de aplicação durante o exame em bovinos.UEL2019-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3463510.5433/1679-0359.2019v40n5p1891Semina: Ciências Agrárias; Vol. 40 No. 5 (2019); 1891-1900Semina: Ciências Agrárias; v. 40 n. 5 (2019); 1891-19001679-03591676-546Xreponame:Semina.
