|Brief Title||Cytapheresis of Volunteer Donors|
|Official Title||Cytapheresis of Volunteer Donors|
- 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.
- To use cytapheresis to collect white blood cells for study.
- Healthy blood donors at least 18 years of age.
Cytapheresis is an automated method/process of cell removal and collection that involves a continuous flow cell separation by centrifugation and the withdrawal of a particular blood component. This allows blood components not collected to be continuously
returned to the donor. Guidance and recommendations for the performance of these procedures are provided in detail in the Standards of the American Association of Blood Banks (AABB) and in the Code of Federal Regulations (CFR).
The study objective is to provide white blood cells obtained by cytapheresis to National Institute on Aging (NIA) researchers for other in-vitro research studies.
The study population consists of healthy males and females 18 years and older. Study subjects are anticipated to be non-patient community volunteers. Individuals will not be excluded based on gender, race or ethnicity. The number of subjects to be enrolled will
be 10, 000. This will allow us to try and maintain 200 active participants in this protocol. Volunteers are screened initially and annually by a health history questionnaire and laboratory testing to screen for bleeding or immune disorders. Participants may undergo a cytapheresis procedure every fifty-six days.
We will collect blood component cells for distribution to NIA research investigators for their studies of the immune system. We will be performing cytapheresis for the collection of 3 7 blood component packs per week. We will need to maintain an active volunteer pool of approximately 200 active volunteers.
