Collecting additional red blood cell (RBC) units using the Haemonetics' MCS-8150 double red blood cell (DRBC) capability can improve operational efficiencies, reduce the risk of blood shortages, and influence the type-distribution of RBC inventories. Portable, durable, and reliable, the MCS-8150 is suitable for both in-center and mobile collection situations. Donor acceptance is high and many report an enhanced donation experience making these DRBC donors more likely to donate again. The use of the MCS-8150 is a major contributor to our blood center's collection growth, allowing us to transform from a major importer of RBC units to a self-sufficient exporter.
