Collection and Distribution of Biospecimens for Novel Research Uses

This is a biospecimen collection study run by iSpecimen, which collects and distributes blood, tissue, and other biological samples from consenting participants for medical research purposes. By connecting researchers who need specific human samples with willing donors, this program accelerates medical discoveries. Participants may be healthy individuals or people with specific health conditions, depending on what types of samples are currently needed by researchers. There is no experimental treatment in this study. Participants simply agree to donate samples (such as blood draws or leftover surgical specimens) for use in approved research projects. You may be eligible if: - You are developmentally at least 7 years old (for research-use-only collections) - You meet the current requirements of an active research collection request - You have reviewed and signed the consent form (or a parent/guardian has done so on behalf of a minor or someone with impaired decision-making capacity) You may NOT be eligible if: - You do not meet the inclusion criteria for the specific research collection request Talk to your doctor to see if this trial is right for you.
