Sandwich assay...yum: Elisa = enzyme-linked immuno sorbent assay. Done by adding serum from a subject to a plate w/antibody against the infection you're testing for on its surface. The antigen (or protein) from the infection binds to the antibody on the plate. Then another antibody to the infection w/color signal chemical attached is added on top and binds to the antigen. If infection is there color can be measured.
