Official Title: Collection of Peripheral Blood, Urine, Sputum, and Bone Marrow From Healthy Donors for Use in In Vitro Research
Brief Summary:
Increased numbers of white blood cells called eosinophils can cause disease. To investigate this disease, researchers need normal blood and bone marrow samples to compare to samples from patients with this problem. This study will collect blood and bone marrow samples from normal volunteers who meet standard blood donor criteria. Some of the samples will be used for genetic testing or future research.
This study will last for about 3 years and will include a maximum of 50 paid volunteers ages 18 to 65.
After a medical screening, volunteers will donate a blood sample and a bone marrow sample, taken from the hip bone, followed by a biopsy that will obtain a small sample of bone and bone marrow. The procedure lasts less than 1 hour. Volunteers may donate repeatedly within the limits set by the study.
