Reference Interval:
0.34 O.D. or less: Negative - No significant level of cysticercosis IgG antibody detected.
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.

| Interpretive Data: |
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.
