Endogenous interfering proteins can be found in any biological matrix, plasma, serum, whole blood, urine, cerebrospinal fluid, oral fluid, sputum, synovial fluid, etc. Many bioanalytical methods to detect analytes in these fluids are based on the interaction of a binding pair, such as an antibody and its antigen or a receptor and its ligand. An interfering protein is any protein that blocks the specific interaction of the binding pair, causing false negative or false positive reactions.
