Comparison of diagnostic tests for the detection of equine infectious anemia antibody

Abstract

Two diagnostic tests are approved for detecting antibody to equine infectious anemia virus: the agar-gel immunodiffusion (AGID) test and the competitive enzyme-linked immunosorbent assay (ELISA). A total of 420 sera from National Veterinary Services Laboratories check sets were tested with the AGID and competitive ELISA. A 100% correlation was obtained. The AGID and competitive ELISA were further used to test difficult samples with low levels of equine infectious anemia antibody (weak positives). A third test (Western blot) was also used with these weak positive samples to resolve any discordant results.
