I would like to clarify two points on your story regarding the opening of the Community BioResources Plasma Donation Center here in Ames.

The process of plasma donation involves running whole blood through a machine which then separates out the various components of the blood. The plasma is separated and stored. The remainder of the blood, including the red blood cells, is returned to the donor along with IV fluids to replace the volume that is being taken away.

This is a well tolerated process and, as mentioned in the story, there is very minimal risk to any donor. Since the red cells are given back to each donor, there is no risk of anemia, and each donor may donate twice a week.

Prior to each donation, there is a stringent questionnaire process and a physical exam to screen for any problem. Besides checking for syphilis, AIDS and hepatitis, there are also other disease screens in place. There is stringent training for all technicians, and strict aseptic technique is followed.

All components that have direct contact with the blood are immediately disposed of after each donation, including needles, tubing and all filters.

As stated in your story, extreme precautions are taken to minimize the possibility of any disease transmission and also to maximize the safety of each donor.
