Advances in the use of monoclonal antibodies for blood group testing.

Until the '80s blood group reagents were composed of human or animal polyclonal antibodies; nowadays they are mainly produced from monoclonal antibodies. In this paper two aspects will be considered; firstly the evolution in the use of monoclonal reagents in France and secondly the quality of these new reagents in comparison with polyclonal reagents. From 1981 to 1995, 17567 batches of blood group reagents were analyzed and controlled by the French Blood Group Reference Laboratory (CNRGS). All data are given in six tables.
