The invention relates to a deer epidemic hemorrhage competitive 
enzyme-linked immunosorbent 
assay kit and a preparation method and a user thereof, the kit comprises an EHDV 
antigen-coated ELISA plate,a 
monoclonal antibody IgG-HRP 
enzyme conjugate, positive serum, negative serum, 20 times of concentrated washing liquid, 10 times of concentrated 
dilution buffer, a substrate I, a substrate II, a substrate III and stop solution. The preparation method comprises the following steps: a, preparing a deer epidemic hemorrhage 
virus ELISA-coated 
antigen, and detecting the safety of the deer epidemic hemorrhage 
virus ELISA-coated 
antigen; b, preparing a 
monoclonal antibody of deer epidemic hemorrhage 
virus and carrying out preparation and identification on the 
antibody-
horseradish peroxidase (HRP) 
enzyme conjugate; c, preparing the positive serum and the negative serum; d, preparing the deer epidemic hemorrhage 
virus antigen-coated ELISA plate; e, preparing the 20 times of the concentrated washing liquid and the 10 times of the concentrated 
dilution buffer, and preparing the substrate I, the substrate II, the substrate III and the stop solution; and f, assembling the kit. The kit is used fordiagnosis, 
quarantine, detection and epidemiological investigation of deer epidemic hemorrhage and is characterized by strong specificity, high sensitivity and the like.
