Test Overview
Test Methodology

ELISA

Test Usage

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 Range *

Negative

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

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.
