tests are the most commonly used tests in the diagnosis of brucellosis;
however, each serological test has some drawbacks. In this study, we
aimed to determine the value of the Brucella Coombs gel test (BCGT) in
the serological diagnosis of brucellosis in comparison with Standard
tube agglutination (STA) and ELISA tests.
Materials and Methods: The study included 42
patients who were considered to have brucellosis as a preliminary
diagnosis. BCGT, Brucella-IgM/IgG ELISA, and STA tests were performed
from serum samples of the patients. The correlation of the diagnostic
tests was analyzed using Cohen’s Kappa Analysis.
Twenty-seven (64.2%) of 42 patients were diagnosed with brucellosis
according to their medical history and clinical and serological tests.
The sensitivity and specificity of BCGT to diagnose brucellosis was
96.2%, and 100%, respectively. The sensitivity and specificity for the
diagnosis of brucellosis 62.9% and 100% for STA, respectively; 33.3% and
66.6% for Brucella-IgM; and 66.6% and 100% for Brucella-IgG.BCGT was significantly correlated with STA (κ= 0.590) and Brucella-IgG (κ=0.539)
BCGT can be utilized as a simple and reliable test in the diagnosis of
brucellosis with high sensitivity and specificity. Nevertheless, the
sensitivity and specificity of BCGT should be demonstrated by
comprehensive studies, including culture-confirmed cases and control
