Platelet concentrates (PCs) obtained using old generation of cell separators contain high number of leukocytes. White cell (WBC) contamination and platelet (Plts) number in PCs obtained from separator II-nd generation CS-3000 and separators III-rd generations CS-3000 plus and Cobe-Spectra have been determined. PCs from new separators contain the same Plts number as PCs from CS-3000. The average leukocyte count in PCs obtained from CS-3000 was 171.26 x 10(6), whereas WBC number in PCs from CS-3000 plus and Cobe-Spectra were 2.87 and 2.54 x 10(6) respectively. In about 85% of PCs obtained from III-rd generation cell separators the leukocyte count did not exceed 5 x 10(6). This count is considered sufficient to prevent alloimmunization of HLA antigens. The determination of WBC count in every PCs allows to select PCs with fewer than 5 x 10(6) leukocytes and to transfuse them without the necessity of using expensive filters for leukocyte removing.
