Реферат: The present invention provides a method for detecting viral infection of a subject by a first Flavivirus species, said method comprising: (a) contacting a sample from said subject with a solid phase support, wherein said solid phase support includes a capture means for immobilising antibody present in the sample that binds a first antigen from a first Flavivirus species; (b) challenging said immobilised antibody with: (i) a second antigen from a second (different) Flavivirus species, wherein the binding of said second antigen thereto suppresses (e.g. blocks) any inherent antigenic binding cross-reactivity towards the second Flavivirus species; and (ii) a labelled first antigen from the first Flavivirus species, thereby forming a labelled antigen-antibody complex; and (c) wherein the presence of labelled complex indicates viral infection of the subject by the first Flavivirus species, and wherein the absence of labelled complex indicates no viral infection of the subject by the first Flavivirus species; and kits for performing said method.
