“…The principle of the Groupamatic system and its mode of operation have already been published [7,8,[10][11][12]191. The blood samples (from voluntary donors) to be tested are collected in vacuum tubes containing EDTA (Becton Dickinson; 0.06 ml of a 15% solution in a 7-mI tube).…”

Red Cell Antibody Screening with the Groupamatic System

These data comprise 1,231,024 routine tests carried out over a 5-year period on voluntary blood donors. The percentage of positive results on the machines varies from 1 to 3% of the total number of samples tested. Antibodies identified either by manual or automated techniques make up 15--20% of the positive screening reactions. Rhesus, Luewis and P systems prevail, whilst Duffy, Kidd and Ltheran systems are absent. This screening has three main advantages: the supply of plasma for our production of test sera, or therapeutic immunoglobulins; protection of the recipient; partial information on the donor's immunohaematological state, especially for the risk of giving him incompatible blood sometimes in the future.

The percentage of positive results on the machines varies from 1 to 3% of the total number of samples tested. Antibodies identified either by manual or automated techniques make up 15-20% of the positive screening reactions. Rhesus, Lewis and P systems prevail, whilst Duffy, Kidd and Lutheran systems are absent.
