To minimise the risk of transmitting HIV and other blood-borne viruses via the blood supply, the Blood Service has policies restricting donations from people who are considered to be in high-risk groups. These are called donation deferral policies.
The Blood Service uses a questionnaire to screen people seeking to donate blood. Potential donors must sign a declaration that they have answered the questions honestly and to the best of their knowledge.
Anyone who has engaged in male to male sex in the previous 12 months is currently deferred from blood donation for a period of 12 months following their last male to male sex.
Deferrals in relation to sexual activities cover people who have engaged in the last 12 months in sex work and people who have had a sexual partner who has ever injected themselves with drugs not prescribed by a doctor or dentist.
A person who has ever injected drugs is precluded for life from donating blood.
