Routine Blood Donation

Voluntary blood donation is the mainstay of the blood system in the United States. Donors usually are > 18 y old, are in good health and afebrile, and weigh > 110 lb (50 kg). Donors are usually limited to 1 unit every 8 wk and 6 donations per year. Patients with a history of hepatitis, HBsAg positivity, insulin-dependent DM, IV drug abuse, heart disease, anemia, or homosexual activity are excluded from routine donation. Patients who may have transmissible diseases are counseled about high-risk behaviors that may put the recipient of the blood at risk. Donor blood is tested for ABO, Rh, antibody screen, HBsAg, anti–hepatitis B core antigen, hepatitis C antibody, anti–HIV-1 and -2, and anti–HTLV-1 and -2.
