Interpretive

Reference Range:

0.34 OD or less

Negative: No significant level of cysticercosis IgG antibody detected.

0.35-0.50 OD

Equivocal: Questionable presence of cysticerosis IgG. Repeat testing in 10-14 days may be helpful.

0.51 OD or greater

Positive: IgG antibody to cysticercosis detected, which may suggest current or past infection.

 

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.
