Detect the presence of CSF IgG antibodies to T. solium if clinical suspicion of cysticercosis exists.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
New York DOH Approval Status
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.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
