Other aspects of each potential donor's health history are discussed as part of the donation process before any blood is collected. Each donor receives a brief examination during which temperature, pulse, blood pressure and hemoglobin (or hematocrit) are measured.

Making donations for your own use during surgery (autologous blood donation) is considered a medical procedure that requires a written prescription and the rules for eligibility are less strict than for regular volunteer donations.
