This is because the majority of transgender people undergo hormone replacement therapy which brings their haemoglobin levels in line with most cis people of the same gender. Haemoglobin testing is conducted in accordance with the gender with which you identify. Blood donation if you are transgenderĪs with all donors, a careful and sympathetic consideration of sexual risk factors is undertaken. NHS Blood and Transplant considers all donors to be the sex and/or gender that they identify as, including nonbinary, genderfluid and agender donors. All donors are addressed using the title and pronouns of their choice. Being transgender does not in any way prevent you from being able to donate.
