Diagnosis of infections of the central nervous system is 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 contaminaton via bloody taps. The interpretation of CSF results must consider CSF-serum antibody ratios to the infectious agent.
