Interpretive
| Reference Range: |
A negative result does not rule out infection. Repeat testing after 4 weeks if clinical suspicion is high. Cross-reaction with antibodies against Echinococcus ssp. have been reported. |

| Use: | Diagnosis of central nervous system infections can be accomplished by demonstrating the presence of intrathecally-produced specific antibody. Interpretation of results may be complicated by low antibody levels found in CSF, passive transfer of antibody from blood, and contamination via bloody taps. |
