Preferred Minimum: 1 mL serum
Absolute Minimum: 0.2 mL serum
Rejection Criteria:
Severely lipemic, contaminated, hemolyzed, or heat-inactivated specimens.

Reference Range:
< 1:20 Negative
Interpretive Data:
Cross-reactions may occur between Brucella and F. tularensis antigens and antisera; therefore, parallel tests should be run with these antigens. A fourfold rise in titer is considered diagnostic. A single serum titer of 1:80 or 1:160 is suggestive of brucellosis when accompanied by a compatible clinical course in a patient with a history of potential exposures.
Methodology:
Semi-Quantitative Agglutination
