Detect presence of IgG antibodies to T. solium in serum if clinical suspicion of cysticercosis exists. 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.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
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.
- Cysticercosis Confirmatory Test
Collect specimen in an SST or red top tube. Centrifuge, aliquot serum into a plastic vial and refrigerate. Parallel testing is preferred and convalescent specimen must be received within 30 days from receipt of the acute specimen. Mark specimens plainly as acute or convalescent.
Test sent to Mayo Medical Laboratories; performed by ARUP Laboratories.
