Just found this on another thread. It's a FOI request on the rules surrounding blood donation for trans people and their partners:
Haemaglobin levels are set for both males and females; there is a legal requirement that these must be met before a donation can be given. Donors who identify themselves as male will be assessed using the male haemoglobin levels and similarly donors identifying as female must have sufficiently high haemaglobin levels to meet the female levels. In addition the selection guidelines state in the additional information that A careful and sympathetic consideration of sexual risk factors needs to be undertaken. A man who has had his gender reassigned as a woman who, as a man, had not had high risk sexual activity, can be accepted if, as a woman, they have a sexual relationship with a man
1: Male sexual partners of transgender women
Male sexual partners of transgender women would not fall under the men who have sex with men deferral policy in their assessment. Other guidance may prevent donation but this situation would not.
2: Male sexual partners of transgender men
Male sexual partners of transgender men can not donate for 12 months as per the men who have sex with men deferral guidance.
8: The criteria by which a transgender woman will be considered by NHSBT to be a woman for the purposes of the MSM deferral.
If a donor states that they are a woman we accept that and do not enquire about their birth gender. As stated earlier in this response, donors who identify themselves as male will be assessed using the male haemoglobin levels and similarly donors identifying as female must have sufficiently high haemaglobin levels to meet the female levels.

If a donor states that they are a man we accept that and do not enquire about their birth gender.
