Serology for brucellosis |
| Overview Risks Results |
| Alternative Names: |
| Brucella serology; Brucella antibody test or titer |
| Normal Values: |
|
A normal results shows no antibodies to Brucella. However, during the first few days to weeks of exposure to an antigen, there may be slight antibody production. As the disease progresses, more antibodies will be present. If a disease is suspected, the test may need to be repeated 10 days to 2 weeks after the first test. A rise in titer (antibody count) is expected. Titers of greater than 1:80 suggest past infection, while titers of 1:160 or higher are suggestive of current infection. Cross-reaction to bacteria such as Yersinia, Francisella, and Vibrio, and immunizations can make the test falsely positive. |
| What abnormal results mean: |
| If antibodies are detected, there has likely been exposure to the Brucella bacteria (possible brucellosis). |
