Clinical trials: Red Blood Cell Disorder
Sickle Cell Disease, Thalassemia
Effects of Transfusion of Older Stored Red Cells
The purpose of this study is to determine the effects of transfusion of fresh and stored blood on patients. The investigators hope to test: whether a similar effect (older stored blood is associated with worse outcomes) is seen…

Diabetes Mellitus, Impaired Fasting Glucose
Effect of Red Blood Cell Survival on a Commonly Used Diabetes Lab Test-HbA1c
Prevention of complications in veterans with diabetes depends heavily on assessment of blood glucose and HbA1c. The HbA1c is a blood test that measures the exposure of hemoglobin (Hb) to a person's average blood glucose over the…

Anemia
Transfusion of Biotinylated Red Blood Cells
The purpose of this research is to study how red blood cells (RBCs) survive in a person's circulation, and how that survival may be different in red blood cells that are donated and stored prior to being transfused.

- b-RBCs (NCT02757898)
- Testing
- Biotin-Labeled Red Blood Cells (RBCs)
- Where
- United States
- Volunteers
- 5 people, healthy volunteers welcome
