Brucellosis antigen refers to the antigen secreted by the cell wall, endotoxin, nucleic acid and other components of Brucella bacteria in human or animal. Brucellosis is an infectious disease caused by Brucella bacteria, which is commonly found in domestic animals and wild animals. Brucellosis can be infected by humans through contact with the blood, urine, milk, etc., of infected animals. Brucellosis antigen tests can be used to diagnose and monitor Brucellosis infection.

Brucellosis antigen detection methods included ELISA, Western blot and immunofluorescence. These methods can detect Brucellosis antigen in serum, urine, cerebrospinal fluid and other samples. Brucellosis antigen testing can help in the diagnosis and monitoring of Brucellosis infection and in evaluating the efficacy of treatment. The method has high sensitivity and specificity, and can diagnose Brucellosis infection at an early stage, thus improving the therapeutic effect.
