Summary

This study collects leftover blood or tissue samples and related health data from people who have already had lab tests at LabCorp. The goal is to build a large, de-identified resource that scientists can use for future research on pregnancy, cancer, and infectious diseases. Some participants may also be asked for additional samples or information if they give permission. No new treatments are being tested here—this is about gathering data to fuel future discoveries.
