NIEHS Repository of Stored Biological Samples for Future Use

Background: Laboratory tests that use blood and urine can provide a great deal of information about human health and disease. To develop even better tests and to improve the ways samples are handled for testing researchers need to experiment with samples from healthy people. Objective: This natural history study will collect blood and urine from healthy people. The samples will build a repository that will be used for all kinds of research. Eligibility: Healthy people aged 18 years or older. Design: Participants will have 1 study visit. The visit will last up to 2 hours. Participants will be screened. They will answer questions about their health history. They will list any medications they take. They will consent to donate samples for research and future use: Blood: Up to 4.5 tablespoons of blood may be collected from a needle inserted into a vein. Urine: Participants will be given a sterile container to provide a sample. Some participants may be asked to provide other types of samples. Some participants may be asked to provide new samples if their first ones are depleted.
