Blood donor eligibility criteria

Blood donor eligibility criteria ensure safety for both donors and recipients. Generally, donors should be healthy, at least 16 or 17 years old (depending on the country), and weigh at least 110 pounds. They should not have recent infections, cold, flu, or illness. Donors must wait periods after certain procedures, vaccinations, or travel to specific regions. People with certain chronic conditions, recent surgeries, or risky behaviors (like drug use) may be deferred. Alcohol should be avoided before donating. Always disclose medical history accurately, as this helps prevent transmission of infections and ensures a safe donation process.
