associated with transmission through transfusion, and assess the risk of transmission and the possible consequences to the blood supply of excluding “at-risk” donors. 6 National donor selection criteria should define conditions of acceptance and deferral for each criterion. 7 Adequate resources, including a sufficient number of qualified and trained staff, should be made available for the consistent and reliable assessment of donor suitability for blood donation. 8 Quality systems should be in place for blood donor selection, including selection criteria, staff training and documentation. 9 Blood transfusion services should have systems for the notification and counselling of individuals who have been deferred from blood donation and for their referral for further management if any abnormalities are found. 10 Blood transfusion services should establish mechanisms for monitoring and evaluation to assess the implementation and effectiveness of donor selection criteria. 11 National regulatory mechanisms for the oversight of the functions of blood transfusion services should include activities related to blood donor selection. 12 National procurement policy and supply systems should encompass the equipment and consumables required for assessing the suitability of blood donors. 6 Technical recommendations These technical recommendations provide a summary of recommendations on donor selection criteria in Sections 4–7, by condition.
