Human plasma is the pale-yellow, liquid portion of the blood and the largest component of human blood, comprising of about 55%. Plasma also contains water, salts, enzymes, antibodies, and other proteins, which help the body control bleeding and infection.
Plasma donations are the source material for the manufacturing of plasma-derived medications. These medicines are used for the treatment and prevention of serious medical conditions such as Hemolytic Disease of the Newborn (HDN) and Rabies infection after exposure to a rabid animal. Plasma donations from healthy adults are critically important to saving lives. For many with rare medical conditions, these are the only therapies available.
