Interpretation
Negative:
The absence of antibodies to Echinococcus species suggests that the individual has not been exposed to this cestode. A single negative result should not be used to rule out infection (see Cautions).
Positive:
Results suggest infection with Echinococcus. False-positive results may occur in settings of infection with other helminths or in patients with chronic immune disorders. Results should be considered alongside other clinical findings (eg, characteristic findings on imaging) and exposure history.
