Detect presence of IgG antibodies to T. solium in serum if clinical suspicion of cysticercosis exists. Consider confirming positive results with Western blot antibody test.
- Patient Preparation
- Serum separator tube.
- Specimen Preparation
- 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.
- Storage/Transport Temperature
- Unacceptable Conditions
- 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)
0.35-0.50 O.D.: Equivocal - Questionable presence of cysticercosis IgG antibody detected. Repeat testing in 10-14 days may be helpful.
0.51 O.D. or greater: Positive - IgG antibody to cysticercosis detected suggestive of current or past infection.
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.
