Immunoassays are subject to interference from endogenous antibodies, especially human anti-mouse antibodies (HAMA) and rheumatoid factor (RF). These interferents are heterogeneous, which means some samples with interfering endogenous antibodies will affect a specific assay and some will not. Using multiple HAMA or RF positive samples will better assess interference more thoroughly.
