About this study

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.
Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The endpoint is to create a biobank of samples which can be used for development and optimization of assays.

    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.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

An observational study of Exposure, run by National Institute of Environmental Health Sciences (NIEHS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The endpoint is to create a biobank of samples which can be used for development and optimization of assays. (time frame: 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01087307, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Nov 2026.
