1. Plasma is the clear, straw-colored liquid portion of blood that remains after red blood cells, white blood cells, platelets and other cellular components are removed. The single largest component of human blood, it comprises about 55 percent, and contains water, salts, enzymes, antibodies and other proteins.

2. Plasma carries out a variety of functions in the body, including clotting blood, fighting diseases and other critical functions.

3. Source plasma donation and blood donation are critically important activities that contribute to saving lives. For many with rare diseases, these are the only therapies available to treat these chronic conditions. Your plasma can be used to create therapies that treat a variety of conditions and diseases, including hemophilia.

4. Plasma-derived therapies are also used in everyday medicine and emergency and critical care situations, as well as in preventive medicine.

5. Patients say they’re grateful to people who donate plasma. During the COVID-19 pandemic, patients who have primary immunodeficiencies and a rare disease called Alpha 1 Antitrypsin Deficiency have made personal pleas asking people to continue donating plasma. Meet additional patients who are helped by plasma-derived therapies.

6. Donors find meaning in donating plasma that will benefit patients who depend on plasma medicines. Meet a few donors and CSL employees who have shared their stories and reasons for donating plasma.

8. In general, plasma donors must be 18 years of age and weigh at least 110 pounds (50kg). All individuals must pass two separate medical examinations, a medical history screening and testing for transmissible viruses before their donated plasma can be used to manufacture plasma protein therapies.
