[Functional characteristics of granulocytes separated by haemonetic cytapheresis (author's transl)].

Granulocytes have been transfused systematically for several years owing to the utilisation of cells separators. It seems profitable to test these granulocytes from a functional standpoint since they are centrifuged and then collected in plastic bags. Several function tests are used and demonstrate that the quality of these granulocytes is on the average diminished without altering them significantly. Morphological studies complementing these qualitative studies demonstrate membrane fusions and partial degranulation.
