title: Testing for e antigen and e antibody by immunodiffusion.
abstract: A rapid and reproducible micro e-ID test is described which allows two out of three HBsAg carriers to be classified as e-Ag or e-Ab. The majority of the remaining one-third of carriers are e-Ab as shown by e-RIA though a few will be e-Ag positive carriers by e-RIA.
