The only identifiable function of Red Blood Cells (RBC) is the delivery of Oxygen. In mammals, RBC is a unique cell because:


The work described in this chapter is based on the function carried out by the cell membrane antigens which are transporting other proteins and molecules into and out of the cell. The question is what are those proteins that are transported? In fact, this question identifies the knowledge gap about RBC role in health and disease. In the next section, some hypotheses will be inducted and deduced through analysis of available background knowledge. The experiments that can proof those hypotheses are described in section 3. This is followed by describing a theory about the role of RBC in health and disease based on the proved hypotheses and how we can benefit from this theory in diagnosing and treating of patients.
