Blood Components 

Each year, Indiana Blood Center performs more than 120,000 whole blood procedures from its volunteer donor base. Whole blood donations are the only procedure offered on mobile blood drives and represent the most common type of donation.

A unit of whole blood must be processed and separated into its components parts. Each component has unique capabilities and is transfused to patients based on their treatment needs. Components of human blood are:

Red Blood Cells

  • Carry oxygen
  • Return carbon dioxide
  • Used to treat anemia, blood diseases and accident victims


  • Microscopic cell fragments
  • Help blood clot
  • About two tablespoons in each pint of blood
  • Used to treat cancer and leukemia patients


  • 92% water, 7% protein, 1% mineral
  • Carries nutrients to body
  • Contains clotting factors
  • Used to treat bleeding disorders and burn victims

Cryoprecipitate Anti-Hemophiliac Factor (AHF)

  • Made from frozen plasma
  • Contains clotting factors
  • Used to treat bleeding disorders

Platelet and Plasma Donations

Maintaining the appropriate and adequate blood supply for patient demand requires Indiana Blood Center to collect not only whole blood, but also apheresis platelets and plasma. In this process, donors are recruited into these programs based on their blood type, the donor's proximity to a donor center and other factors. Simply put, apheresis donations allow phlebotomists to separate a donor's whole blood into the desired component part and return the red blood cells and other components to the donor at the time of donation.
