[Determination of Lewis and P blood group phenotypes with the aid of the Autogrouper 16C].

For more than one year, we are using the Autogrouper 16 C, at the beginning the prototype machine according to Rechsteiner, for ABO, Rhesus and Kell determinations and now Lewis and P grouping increases its possibilities, using free chanels. The connection to a PDP 11 computer enables us to sophisticate the interpretation of results and to use, for example, unadsorbed reagents.
