Mnemonic: BRUC IGG

Methodology: Enzyme-Linked Immunosorbent Assay
Performed: Tue, Thu
Reported: 1-6 days
Specimen Required: Collect:  One 4 mL serum separator tube or plain red.

Transport:  1 mL serum at 2-8°C. (Min: 0.2 mL)  Submit specimen in an ARUP Standard Transport Tube.

Pediatric Collection/Transport:  0.1 mL serum, frozen.

Remarks:  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:  Hemolyzed, lipemic, heat-inactivated, or contaminated specimens.

Stability:  After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year
Reference Interval:
0.89 IV or less: Negative - No significant level of detectable Brucella IgG antibody.
0.90-1.10 IV: Equivocal - Questionable presence of Brucella IgG antibody.  Repeat testing in 10-14 days may be helpful.
1.11 IV or greater: Positive - IgG antibody to Brucella detected, which may indicate current or past infection.
Interpretive Data: The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.  This assay may not detect antibodies to B. canis.
CPT Code(s): 86622
