Summary Introduction
Introduction:
The blood is analyzed for the existence of a specific antibody and antigens by a method termed as serology. There are wide range of serological tests available to recognize the antigens or antibodies in the blood. Using tagged or labelled antibody to identify an antigen is an altered form of serological testing method, for example ELISA, fluorescent antibody tests (direct and indirect), and immunoblotting tests. ELISA uses enzyme labelled anti-antibody as a reagent that attaches to the antibody (binds to antigen of choice).
