Cautions

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. Antibodies to other parasitic infections, particularly echinococcosis, may cross-react in the cysticercus IgG enzyme-linked immunosorbent assay (ELISA). Confirmation of positive ELISA results by the cysticercus IgG antibody Western blot is thus recommended.
