Detect the presence of CSF IgG antibodies to T. solium if clinical suspicion of cysticercosis exists.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Transfer 1 mL CSF to an ARUP Standard Transport Tube. (Min: 0.3 mL)
Serum. Contaminated, heat-inactivated, hemolyzed, icteric, or lipemic specimens.
Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|0.8 IV or less||Negative - No significant level of cysticercosis IgG antibody detected.|
|0.9 - 1.1 IV||Equivocal - Questionable presence of cysticercosis IgG antibody detected. Repeat testing in 10-14 days may be helpful.|
|1.2 IV or greater||Positive - IgG antibodies 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.
A negative result does not rule out infection. Repeat testing after 4 weeks if clinical suspicion is high.
Cross-reaction with antibodies against Echinococcus ssp. have been reported.
