                                           specimen (collected 3-4 weeks after

                                           initial specimen) suggested if clinically

                                           warranted.

                             > 1.20   Antibody detected   

 

Detection of serum antibodies to Echinococcus plays an

important role in the diagnosis of hydatid disease, since infected

individuals do not exhibit fecal shedding of Echinococcus eggs.

Increasing antibody values between acute and convalescent

specimens is considered evidence of recent or current infection.

The frequency of a positive result for serum antibodies to

Echinococcus is higher in patients with active cysts in the liver

than in patients with hydatid cysts in the lung or calcified cysts.

Echinococcal antibodies may persist for years after cyst removal.

Serologic crossreactivity between Echinococcus and

Cysticercus may occur; additional testing for Cysticercus and

Echinococcus antibodies may therefore be warranted.
