Blood: Donors

NHS Blood and Transplant (NHSBT) tests for haemoglobin levels rather than iron levels ahead of blood donation. If the test shows that the haemoglobin is low, the donor is deferred and information is provided on how they can increase haemoglobin levels through altering their diet, and book an appointment with their general practitioner if levels are particularly low. On average, 7% to 11% of donors are deferred because of low haemoglobin levels, but this rises to 12% of black heritage donors and to 25% of female black heritage donors. These deferrals impact on donor retention, as donors deferred for low haemoglobin are less likely to return.

Currently there are no plans to review minimum haemoglobin levels to donate blood. Donors whose haemoglobin levels are below safe levels to donate are deferred in accordance with the Blood Safety and Quality Regulations 2005 and the guidance issued by the Joint UK Blood Transfusion and Tissue Transplantation Services Professional Advisory Committee (JPAC) which states ‘taking a donation from a person with a haemoglobin concentration below the recommended value may make them anaemic’.

Increasing diversity in the donor base is a priority for NHSBT, so they can provide matched blood for more patients, including those with rare blood types commonly found in black, Asian, and minority ethnic women. NHSBT provides grants to community and faith groups to encourage donation, including in black, Asian, and minority ethnic communicates. The Department provided seed funding for NHSBT to increase its collection capacity, particularly in diverse areas where higher proportions of the population have rare blood types, including Brixton and Brighton.
