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.
