Abstract. The authors studied the degree of qualitative and quantitative deleucocytation of whole blood that can be obtained by washing and filtering. Based on the studies of 20 samples of blood it was established that successful deleucocytation can be expected only it combined procedures of washing and filtering are employed. The purpose of our present investigations was to determine to what extent can whole blood be deleucocyted by using current methods of blood preservation, or by combining these methods, as well as to assess the degree of damaging effects on red blood cells produced by these methods.

Summary Acidification of the plasma is shown to be just as favourable for the preparation of a nonaggregating concentrated leucocyte suspension as for the preparation of platelet concentrates, a procedure generally accepted.
