Additional information: |
It is well known that heterophilic antibodies in human serum can react with reagent immunoglobulins, interfering with in vitro immunoassays. Patients routinely exposed to animals or to animal serum products can be prone to this interference and anomalous high values can be observed. Additional information may be required for diagnosis. | |
