Interpretive Information:
| <9 U Negative: | No significant level of cysticercosis IgG antibody detected. |
| 9-11 U Equivocal: | Recommended repeat testing in 2-4 weeks with fresh sample. |
| >11 U Positive: | IgG antibody 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 cystercosis antibody, IgG by Western blot is recommended.
