Sensitive and reliable serologic methods are necessary to confirm the diagnosis. In this study, Ag B and Psc Ag were purified as two specific parasitic antigens and evaluated by Dot blotting used on the serum of hydatidosis patients and control group in order to identify the most sensitive and specific subunits. Materials and Methods: In an analytic and comparative study, serum samples collected from 22 patients under operation of hydatid cyst. As a control group, 4 patients with acute toxoplasmosis, 4 patients with leishmaniasis, 4 patients infected by non-hydatid cestods(Tenia saginata and H.nana) and 4 normal subjects were included in this investigation. Infected sheep’s liver and lung were used for the preparation of antigen. Cyst fluid containing protoscoleces was extracted and then partially purified with a protein A column. AgB and Psc Ags were interacted with hydatid and control sera, with Dot blot method and sensitivity and specificity of these antigens were evaluated.  Results: Sensitivity and specificity were estimated 95.9% and 81% respectively, for AgB and 100% and 63% respectively, for Psc Ag in Dot blot Method. Conclusion: Evaluation of sensitivity and specificity of AgB and Psc Ag using Dot blotting revealed that AgB has high value for diagnosis of hydatidosis. and presumably can help physicians to diagnose hydatid cyst easier than other routine tests.
