How often can you donate plasma legally?

The FDA allows plasma donation up to twice per 7-day period, with at least 48 hours between donations. This equals a maximum of about 104 donations per year, though the FDA caps the annual total at 110 liters of plasma. Most regular donors donate 6–8 times per month. The 48-hour minimum exists because your body needs time to replenish plasma proteins (primarily albumin, immunoglobulins, and clotting factors). Donating more frequently than twice per week has been linked to protein deficiency and increased side effect rates — the limit exists to protect donor health, not just to regulate supply.

What is plasma used for after donation?

Donated plasma is used to manufacture plasma-derived medicines (PDMs) that treat life-threatening conditions: immunoglobulin therapy for immune deficiencies, hemophilia A and B treatment (clotting factors VIII and IX), alpha-1 antitrypsin therapy for hereditary lung/liver disease, albumin for trauma and burn patients, and rabies/tetanus hyperimmune globulins. The US supplies approximately 70% of the world's plasma-derived medicines, largely because the US is one of the few countries that compensates plasma donors — higher compensation drives higher donation volume. Your plasma donation directly contributes to treatment of patients with rare, chronic diseases.

What disqualifies you from donating plasma?

Permanent disqualifications: HIV/AIDS, hepatitis B or C, human T-cell lymphotropic virus (HTLV), certain cancers, Creutzfeldt-Jakob disease (CJD), history of IV drug use, and a history of receiving money for sex. Temporary deferrals vary by center and condition: recent tattoos or piercings (3–12 months), pregnancy and postpartum (6 months), recent illness or fever (recover fully first), active antibiotic treatment, recent travel to malaria zones (12 months), and some medications. Low hematocrit (iron) is the most common deferral reason for regular donors — addressable through diet and supplementation.
