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 contamination
via bloody taps. The interpretation of CSF results
must consider CSF-serum antibody ratios to the infectious
agent.
