Increased numbers of white blood cells called eosinophils can cause disease. To investigate this disease, researchers need blood, urine, sputum, stool, cerebrospinal fluid, skin and/or bone marrow samples to compare to samples from patients with this problem. Some of the samples will be used for genetic testing or future research. This study will last for about 10 years and will include a maximum of 50 paid volunteers ages 18 to 65.
