Multicomponent donor apheresis in the Americas

Multicomponent donor apheresis utilizes apheresis technology to collect combinations of red blood cells, platelets and plasma units. The United States has embraced this technology to the greatest extent of the countries in the Americas. As whole blood and apheresis collection have increased, so have the donor deferrals based on potential exposure to infectious agents. However, hemoglobin/hematocrit deferrals still remain the largest upfront deferral for volunteer donors. As the technology is refined in future years, multicomponent donor apheresis may become the predominant method of collecting blood products from donors.
