Cytapheresis of Volunteer Donors

Study Description

Cytapheresis of Volunteer Donors

Background: - National Institute on Aging researchers are looking at studies that require large numbers of white blood cells for lab use. Standard blood samples do not provide enough white blood cells for these studies. Researchers want to use cytapheresis to collect white blood cells from volunteer donors. This procedure can collect larger amounts of white blood cells and reduce the amount of fluid and other cells that are lost. Objectives: - To use cytapheresis to collect white blood cells for study. Eligibility: - Healthy blood donors at least 18 years of age. Design: - Participants will be screened according to the usual blood donation procedures. - Participants will provide white blood cells through cytapheresis. The blood cells will be collected in a machine that separates the white blood cells from the rest of the blood. The rest of the blood will be returned to the donor. - Participants may have this type of donation every 56 days (six times per year). They will be asked to become a repeat donor. A donation schedule may be set up. - Once a year, participants will have blood tests to continue to be eligible as a donor.
