22579 Echinococcus Ab, IgG, Serum (ECHNO)

Echinococcus Ab, IgG, Serum (ECHNO)
Test Code: ECHINSO
Synonyms/Keywords
Echinococcosis
Hydatiosis
Hydatic disease
Cystic echinococcal disease
Alveolar echinococcal disease
Useful For
Detection of antibodies to Echinococcus species, including E multilocularis and E granulosus. Positive results should be interpreted alongside clinical findings (eg, characteristic findings on imaging) and suitable exposure history. A single negative result should not be used to rule out infection. False-positive results may occur in individuals with other helminth infections or chronic autoimmune conditions.

Negative​
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).

Equivocal: consider repeat testing on a new serum sample in 1 to 2 weeks.

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 and exposure history.
