Comparison of Plateletapheresis with Two Cell Separators using Identical Donors

* = p < 0.005; 1 product 12 products 16 products WBC < 106 106 107 108 16 products All products had < 1 ml of red cells. PLT yields were the same, but significantly less donor blood was processed by the COBE, giving better efficiency for equivalent donor PLT counts. The COBE procedure used more ACD-A, but resulted in no significantly greater change in donor Ca++, although more hypocalce-mic symptoms (facial paresthesias) were noted by COBE donors. Both FEN and COBE provided high quality PLT collections, with COBE resulting in significantly less WBC contamination but more donor symptomatology.
