Blood donors will be questioned on sexual activity, not orientation

Male blood donors will no longer be asked if they have had sex with another man, but — along with women — will be asked in future if they have had multiple sexual partners and anal sex.

Canadian Blood Services says it plans to submit its recommendation to end the gay blood ban to Health Canada within the next two weeks.

Dr. Isra Levy, Blood Services’ vicepresident of medical affairs, said at the organization’s board meeting Friday that its submission will say sexual behaviour, not sexual orientation, determines risk of transmission of HIV.

Levy said it will recommend that men giving blood no longer be asked if they’ve had sex with another man.

“If the submission is approved we will be able to focus the donor screening on high-risk sexual behaviour. Specifically the change would allow us to stop asking men if they have had sex with ... any other man,” he said.

The evidence was now “overwhelming that this change ... will not compromise safety in any way,” he said.

The blood service said it had safety evidence from risk modelling, its own research program and international research, including from the United Kingdom.

He said the Canadian blood service had been in weekly contact with the U.K. blood service, which has already ended its gay blood ban.

Canada’s blood service plans to recommend to Health Canada that screening questions be changed along U.K lines to end discrimination against gay men who want to give blood.

Levy said blood services has done extensive modelling and the new criteria would allow screening for HIV “regardless of gender or sexual orientation” while protecting the safety of the blood supply.

He said safety remained “paramount” and “blood safety would not be compromised by our proposed approach.”

Canadian Blood Services tests all donated blood products for viruses and diseases, including HIV, but tests may not be 100 per cent accurate.
