White blood cells assist in resisting infections, and platelets have a huge role in clotting. Typical symptoms of a red blood cell issue are fatigue, shortness of breath, difficulty concentrating, muscle weakness and fatigue, and an increased heart rate. Platelet counting methods were used to identify radiation doses, which then led to studies of effects in the bone marrow and the benefits of bone marrow transplants.
