Special Info
Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Label specimens plainly as 'acute' or 'convalescent.' Contaminated, heat-inactivated, hemolyzed, or severely lipemic specimens will be rejected. This test is New York DOH approved.
Clinical Info
Cross-reactions may occur between Brucella and F. tularensis antigens and anitsera; 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.
