Study Notes

Polycythemia and Therapeutic Phlebotomy

  • Some individuals referred for therapeutic phlebotomy are as healthy as volunteer blood donors, such as those with hereditary hemochromatosis.
  • True patients require close medical supervision during the therapeutic phlebotomy process.

Physical Examination for Blood Donation

  • General Appearance: Defer donation if the donor looks ill, appears intoxicated, or is excessively anxious.
  • Temperature: A donor's temperature must not exceed 37.5 °C (99.5 °F) to be eligible.
  • Pulse: Should be regular, with a frequency between 60 and 100 beats per minute.
  • Brucellosis: Donors with a history of brucellosis are deferred for 2 years following their last febrile episode.

Blood Donation Eligibility Statements

  • Hepatitis C History: A donor with a history of hepatitis C is permanently deferred from donating blood.
  • Anemia and Blood Loss: Donors with inadequate oxygen-carrying capacity due to anemia or blood loss are not eligible.
  • Coagulation Concerns: Insufficient coagulation proteins or platelets may hinder adequate hemostasis and affects donor eligibility.
