Detect presence of IgG antibodies to T. solium in serum if clinical suspicion of cysticercosis exists.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Serum separator tube.
Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent."
CSF. Contaminated, heat-inactivated, hemolyzed, icteric, or lipemic specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Effective April 3, 2019
|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.|
Seroconversion between acute and convalescent sera is considered strong evidence of recent infection. The best evidence for infection is a significant change on two appropriately timed specimens where both tests are done in the same laboratory at the same time.
Patients with collagen vascular diseases, hepatic cirrhosis, schistosomiasis, and other parasitic infections can produce false-positive results. There is a strong cross-reaction between cysticercosis and echinococcosis positive sera. Confirmation of positive ELISA results by the cysticercosis antibody, IgG by Western blot is recommended.
