An evaluation of an agar gel diffusion test with crude and purified antigens in the diagnosis of hydatid disease

Abstract

The sensitivity of the indirect haemagglutination test for the diagnosis of hydatid disease, although high, is insufficient. Agar gel diffusion tests for the diagnosis of this disease have not received much attention in the past and have been considered unsatisfactory. The authors propose such a test and evaluate its results in comparison with those of the indirect haemagglutination test.
