Test Overview
Test Methodology

ELISA

Test Usage

Diagnosis of central nervous system infections can be accomplished by demonstrating the
presence of intrathecally-produced specific antibody. Interpreting results may be complicated by low antibody levels found in CSF, passive transfer of antibody form blood, and contamination via bloody taps. The interpretation of CSF results must consider CSF-serum antibody ratios to the infectious agent.
