Logan received his first blood transfusion just hours after his birth. Since then he's received blood on a regular basis. When Logan was three he was diagnosed with pyruvate Kinase deficiency, a form of chronic anemia. The anemia causes Logans red blood cells to break down easily, which causes severe fatigue and other complications. People with this condition need blood transfusions to survive. Logan is living proof of the power of blood donors. Generous blood donors are Logan’s lifeline.
