EFFECT OF FILTRATION, STORAGE AND PLATELET SUSPENSION MEDIA ON PLATELET INDEXES

We describe a new approach for assessing filtration-induced changes in cellular indices of platelet concentrates at the beginning and the en d of storage, using pairs of identical packs. The results revealed tha t post-filtered products did not store as well as their counterparts. Filtration did not induce any significant changes on aggregation as de termined by spontaneous aggregation nor was there a disparity between leucocyte peroxidase/basophil count. We recommend filtration on day 2 which causes minimal loss of platelets and less change in the mean pla telet volume.
