| Potential cross-reacting antibody or control group (no. of sera tested) | No. (%) of sera with a positive or equivocal result bya: |
|
|---|---|---|
| EIA | SAT | |
| Healthy control (50) | 3 (6.0)b | 0 (0.0) |

a
SAT, standard tube agglutination test; EIA, enzyme immunoassay.
b
These 3 samples were equivocal by the Brucella IgG EIA.
c
These samples were positive by the Brucella IgG EIA.
