Researchers would like to determine normal ranges for hormone levels and to learn more about the genetics involved in hormone production and action. Researchers will take samples of blood, urine, saliva, and stool from healthy children ages 5-17 in order to study different aspects of hormones.
Establishing a range of normal hormone levels in children will make diagnosing illnesses with abnormal levels of hormones much easier. Hormone levels in the body can change throughout the day. By collecting samples at different times researchers hope to learn more about the normal daytime and nighttime patterns of hormone secretion. Because some hormone levels change with body size, researchers will also take measurements of patient's body composition.
This study will involve children and observe them as inpatients or as outpatients. <TAB>
