Brucella Antibody : 0050135

Mnemonic: BRUC

Methodology: Bacterial Agglutination
Performed: Mon-Sat
Reported: 2-4 days
Specimen Required: Collect:  One 4 mL serum separator tube.

Transport:  1 mL serum at 2-8°C. (Min: 0.5 mL) Submit specimen in an ARUP Standard Transport Tube.

Pediatric Collection/Transport:  0.2 mL serum at 2-8°C.

Remarks:  Separate serum from cells ASAP. Acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Please mark specimen plainly as "acute" or "convalescent."

Unacceptable Conditions:  Severely lipemic, contaminated, hemolyzed, or heat-inactivated specimens.

Stability:  After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
< 1:80 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 greater than or equal to 1:160 is considered diagnostic. A single serum titer of 1:160 or 1:320 is suggestive of brucellosis when accompanied by a compatible clinical course in a patient with a history of potential exposures.
CPT Code(s): 86622
