Acerca de la investigación
Background:
\- Researchers are interested in developing a registry protocol to obtain biologic and environmental samples anonymously from adult volunteers for use in laboratory tests and studies. The samples will be used to determine if new tests are sufficiently valid and precise to be used in research studies and for quality control purposes.
Objectives:
\- To provide a registry of samples for test development, validation, analysis, and quality control at the National Institute of Environmental Health Sciences.
Eligibility:
\- Male and nonpregnant female volunteers at least 18 years of age.
Design:
- Samples to be collected will include blood, urine, saliva, household dust, cheek cells, hair, nasal cells, stool, nail clippings, exhaled breath condensate, or sperm.
- Specimens may be collected during a one-time sample collection, or participants may be asked to provide specimens on several occasions over a specified period, not to exceed 1 year.
- Eligible participants will be asked to come to the clinical research unit to have their blood drawn and any noninvasive samples retrieved. Prior to blood draw, researchers will administer a brief past 24-hour questionnaire for research purposes. Specimens will be collected using standard clinical protocols.
- Participants will receive monetary compensation for providing samples for this protocol.

We propose a sample collection registry protocol for use in obtaining biologic and environmental samples anonymously from adult volunteers for use in laboratory assay evaluation. The samples will be used to determine if new tests are sufficiently valid and precise to be used in research studies and for quality control purposes. In studies involving the storage and analysis of laboratory specimens, it is essential to evaluate the performance of available assays and to actively assess the impact of storage and handling on the quality of samples and laboratory analyses. Specifically, it is essential to 1) demonstrate that an assay is sufficiently reproducible and stable over time such that differences in levels among individuals in the population can be detected; 2) evaluate assay reliability by sending blinded anonymous samples along with study samples to testing labs for quality control purposes; 3) test proposed laboratories or methods by using replicate samples from the population in order to choose the laboratory or method with the greater precision, and; 4) assess how sample collection, handling, and storage procedures affect measured levels of specific analytes to allow for informed decisions about whether to proceed with a specific analysis. Under this protocol, assays could include evaluation of immunologic parameters, genes and gene products, peptides, proteins, hormones, lipids, viability of cells, evaporation and dilution effects, chemical toxins and their metabolites, micronutrients, metals and more. For some samples, lymphocytes will be extracted for use in studies of lymphocytes and/or immortalized cells. Samples to be collected will include blood, urine, saliva, household dust, cheek cells, hair, nasal cells, stool, nail clippings, exhaled breath condensate, sperm samples, skin cells, and/or sputum. In addition, a pulmonary function test (PFT) may be conducted to collect lung function information. Since it is important to collect samples from the general population, this protocol covers collection of samples from non-pregnant adults (male and female, age 18+). Specimens may be collected during a one-time sample collection, or participants may be asked to provide specimens on several occasions over a specified period, not to exceed one year.

Medidas principales
The endpoint is to create a biobank of samples which can be used for development and optimization of assays.
Plazo: 24 hours
The objective of each collection is to generate a small pool of biological or environmental samples with which to develop and test specific laboratory assays, to maintain freezer and specimen handling quality control, to have blinded quality control specimens for testing labs, and to assess exposure variability over time.
