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

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