Methodology: Enzyme-Linked Immunosorbent Assay
Performed: Tue, Thu Reported: 1-6 days |
| Specimen Required: | |
|
Collect: One 4 mL SST 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.

| 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.
