Evaluation of a New and Rapid Serologic Test for Detecting Brucellosis: Brucella Coombs Gel Test

Hayrunisa Hanci, Hakan Igan and Muhammet Hamidullah Uyanik

Abstract:
Background: Many serological tests have been used for the diagnosis of human brucellosis. A new serological method is identified as Brucella Coombs gel test based on the principle of centrifugation gel system similar to the gel system used in blood group determination. In this system, if Brucella antibodies were present in the serum, antigen and antibody would remain as a pink complex on the gel. Otherwise, the pink Brucella antigens would precipitate at the bottom of the gel card system. Objective: In this study, we aimed to compare the Brucella Coombs gel test, a new, rapid screen and titration method for detection of non-agglutinating IgG with the Brucella Coombs test. Materials and Methods: For this study, a total of 88 serum samples were obtained from 45 healthy persons and 43 individuals who had clinical signs and symptoms of brucellosis. For each specimen, Rose Bengal test, standard agglutination test, Coombs test and Brucella Coombs gel test were carried out. Results: Sensitivity and specificity of Brucella Coombs gel test were found as 100.0 and 82.2%, respectively. Conclusion: Brucella Coombs gel test can be used as a screening test with high sensitivity. By the help of pink Brucella antigen precipitation, the tests’ evaluation is simple and objective. In addition, determination of Brucella antibody by rapid titration offers another important advantage.
