The relative efficacy of Ouchterlony's double diffusion (ODD), Wadsworth's gel diffusion (WGD) and counter-immunoelectrophoresis (CIE) is reported for serodiagnosis of allergic bronchopulmonary aspergillosis (ABPA). Of the 50 sera taken from patients with confirmed or suspected ABPA, serum precipitins were demonstrated against Aspergillus fumigatus by CIE, WGD and ODD in sera from 34, 31 and 25 patients, respectively. The results were negative by the three methods in sera taken from 10 healthy volunteers. It is concluded that CIE followed by WGD is more efficacious than ODD for serodiagnosis of ABPA.
