Delivery Instructions:
Submit specimen to laboratory as soon as possible after collection.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
