1,000 volunteers needed to unlock secrets of sickle cell trait
NCT ID NCT06071377
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will follow 1,000 adults who have sickle cell trait (SCT) to better understand how it affects their health. Researchers will collect blood and urine samples to measure hemoglobin levels, blood cell properties, and signs of kidney or clotting problems. The goal is to learn why some people with SCT develop complications while others do not.
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 study could reveal which people with sickle cell trait are at higher risk for health problems like kidney disease, helping doctors monitor them better.
- What could go wrong
- This is an observational study, not a treatment trial. It will not test any drug or therapy, so it cannot directly improve health. Results may take years and might not lead to clear changes in care.
