Special Info
If Brucella antibody screen IgM or IgG is reactive, then confirmation by Brucella total antibody agglutination testing will be performed at an additional cost, and this could delay turnaround time.
Clinical Info
To aid in diagnosis of brucellosis. Brucella canis, a rare cause of brucellosis, may not be detected by this method. This test utilizes antigen derived from Brucella abortus strain W99. However, significant cross-reactivity exists for other Brucella species (except B. canis), therefore, the assays should not be used to differentiate infection at the species level. Detection of specific IgM or IgG-class antibody to B. melitensis and B. suis by this method has not been determined.
