What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing

Summary

This study collects biological and environmental samples—like blood, urine, saliva, and household dust—from over 5,000 healthy adults. The goal is to create a biobank that researchers can use to develop and validate new lab tests for environmental health studies. Participants provide samples over up to one year and receive compensation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this registry will provide high-quality samples to improve the accuracy of lab tests used in environmental health research.
What could go wrong
This is a sample collection study, not a treatment trial. It does not test any therapy or intervention, so there is no direct benefit to participants.
