Stability
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 6 months (avoid repeated freeze/thaw cycles)  
Reference Interval
 < 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 brucellosiswhen accompanied by a compatible clinical course in a patient with a history of potential exposures.
