Reference Range:
0.000-0.890 IV Negative - No significant level of Echinococcus IgG antibody detected. 0.900-1.009 IV Equivocal - Questionable presence of Echinococcus IgG antibody detected. Repeat testing in 10-14 days may be helpful. 1.210 IV or greater Positive - Presence of IgG antibody to Echinococcus detected, suggestive of current or past infection.
Interpretive Data:
Patients with collagen vascular diseases, hepatic cirrhosis, schistosomiasis, and other parasitic infections can produce false- positive results. There is a strong cross-reaction between echinococcosis- and cysticercosis-positive sera.

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.
Methodology:
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
