What is the minimum donor hemoglobin required for presurgical autologous donation?

• A. 9.5 g/dL
• B. 11.0 g/dL
• C. 10.5 g/dL
• D. 12.0 g/dL

Answer: (B)

Presurgical autologous donation requires the donor to have enough hemoglobin to safely tolerate the phlebotomy and still maintain adequate oxygen delivery during surgery if blood loss occurs. The commonly accepted minimum Hb for this procedure is about 11.0 g/dL (roughly hematocrit ~33%). This threshold balances safety with the goal of providing enough autologous blood for the patient, without unnecessarily delaying donation. Values below this are generally deferred or followed with iron optimization, while higher values meet safety but exceed the minimum requirement.
