Platelet activation by riboflavin and UV light: is it really the other side of the coin?

INTRODUCTION: Nowadays transfusion safety is still put at risk by contamination of pathogens. The Mirasol PRT System blocks the replication of pathogens and white blood cells. Our goal was to quantify the activation of platelets after treatment with the Mirasol device. MATERIALS AND METHODS: From September to December 2013, 131 platelet collections were studied using a simple flow cytometric strategy. RESULTS: There was a significant correlation between the percentage of platelet activated before and after the treatment. CONCLUSION: Our results induced us to think that the activation of platelets after treatment was acceptable.
