Counter immunoelectrophoresis as a rapid screening test for amoebic liver abscess.

Abstract
Counter immunoelectrophoresis using cellulose acetate as the supporting medium was used as a rapid screening test for amoebic abscess. All sera from 40 [human] cases gave positive results. No false positives were obtained, but the results in intestinal amoebiasis were less reliable. An attempt was made to account for discrepancies in previous reports.
