Methodology
Enzyme Linked Immunosorbent Assay
Reference Range
0.00 - 0.89 IV: Negative -
No significant level of Echinococcus
IgG antibody detected.
0.90 - 1.09 IV: Equivocal -
Questionable presence of Echinococcus
IgG antibody detected. Repeat testing in
10 - 14 days may be helpful.
≥1.10 IV: Positive: Presence of IgG antibody to
Echinococcus detected, suggestive of
current or past infection. Patients with
collagen vascular diseases, hepatic cirrhosis,
shistosomiasis, and other parasitic infections
can produce false-positive results. There is a
strong cross-reaction between echinococcosis-
and cysticercosis- positive sera.
