[Study of the platelet concentrate obtained with the MCS cell separator of the Society of Haemonetics].

The purpose of this work is to propose several platelets MCS programs which could be included in Haemapheresis Units. In the near future, one of our target is to decrease the transfusion risk. To reach this goal, it is very important to decrease the production of standard platelet concentrates from blood units by replacing them with platelet concentrates. For this work, we used MCS monitor from Haemonetics, equipped with two pumps. We have tested the platelet procedures by the mean of three programs (2.61, 3.61, 4.11 whole blood processed). The results showed good platelet yield (3.55, 4.82 and 5.37 1.10(11) for each program) with good quality of platelets up to 3 days storage (aggregation, beta-thromboglobulin release). The MCS machine could complete platelet apheresis systems and might in the future replace the classical standard platelet concentrates.
