Clinical trials: Red Blood Cells
Sickle Cell Disease, Sickle Cell Anemia
Red Cell Half Life Determination in Patients With and Without Sickle Cell Disease
Background: Sickle cell disease (SCD) is an inherited blood disorder. It results from a single genetic change (mutation) in red blood cells (RBCs). RBCs are the cells that carry oxygen to the body.
