Clinical Significance
The presence of Human Anti-mouse Antibody (HAMA) has been associated with patients receiving injections of Murine Monoclonal Antibody (MAB) for diagnostics and/or therapeutic purposes. HAMA produced in response to monoclonal antibody therapy may interfere with therapeutic efficacy. Therefore, it is recommended that baseline HAMA levels are determined prior to the initiation of therapy with murine-derived proteins.
