| Comments | |||||
| 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. | |||||
