The purpose of this study is to demonstrate that small amounts of a person's own red cells, when treated with an enzyme to make A-ECO Red Blood Cells, can be safely re-infused, repeatedly. Each participant will have some blood drawn, treated with an enzyme, washed and re-infused five times. Additional samples of blood will be drawn for testing and evaluation.
