BIOQUIMICO PLASMÁTICO DE CÃES: EFEITOS DOS DIFERENTES ANTICOAGULANTES EM COMPARAÇÃO COM O SORO

Abstract

Different types of anticoagulants are used in the routine of a veterinary clinic, which are chosen based on the exam to be performed. Agitated, aggressive, of hard contention and small size animals can be a limiting factor when it is wished to separate samples into tubes with different anticoagulants. Therefore, this study had as the objective evaluate the effects of anticoagulants: EDTA, sodium citrate and sodium fluorite associated with EDTA, in the results of routine plasma biochemistry performed in dogs and compare it with serum. Blood samples of 10 clinically healthy dogs were collected and placed in different tubes with each anticoagulant and one without to obtain serum. Albumin, alanine aminotransferase (ALT), calcium, total cholesterol, creatine, phosphorus, glucose, total protein (PT) and urea concentrations were measured by spectophotometric. It was found that plasma obtained with EDTA anticoagulant resulted in dosage alterations for glucose, cholesterol and calcium. Samples obtained with sodium citrate presented results lower than serum in all analyzed parameters, except for ALT. The anticoagulant sodium 34 Colloquium Agrariae, v. 11, n.1, Jan-Jun. 2015, p.33-41. DOI: 10.5747/ca.2015.v11.n1.a116 fluorite with EDTA only didn’t result in statistical differences when compared to serum in the parameters of urea and glucose. Thus, serum is the most trustworthy sample to determine the biochemical profile of dogs, however some biochemical’s can be performed with plasma with EDTA such as creatine, ALT, urea, albumin, PT and phosphorus.
