Specimen Instructions:
Acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of acute specimens. Please mark specimens plainly as "acute" or "convalescent."
Reference Range:
0.235 OD or less: Negative - No significant level of Echinococcus IgG antibody detected. 0.236-0.299 OD: Equivocal - Questionable presence of Echinococcus IgG antibody detected. Repeat testing in 10-14 days may be helpful. 0.300 OD 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:
Enzyme-Linked Immunosorbent Assay
