Human anti-mouse antibodies

Arch Pathol Lab Med. 2000 Jun;124(6):921-3. doi: 10.5858/2000-124-0921-HAMA.


Human anti-mouse antibodies (HAMA) are human immunoglobulins with specificity for mouse immunoglobulins. This topic currently is of interest because of the increased use of monoclonal mouse antibodies as diagnostic reagents both for in vitro laboratory measurements and for in vivo imaging studies. Monoclonal mouse antibodies also are being used therapeutically. This short article reviews the production of HAMA in patients receiving monoclonal antibodies and illustrates the potential ways that HAMA can interfere with immunoassay measurements. Methods for measuring and neutralizing HAMA also are discussed.
