Trans individuals

Eligibility criteria for trans individuals

In recent years, an increasing number of potential donors have identified as trans. That’s why we added national criteria specific to trans blood donors in 2016.

Before the national criteria was implemented, trans donors who visited one of our blood donation events may have experienced a certain degree of uncertainty about how the screening process would apply to them. By standardizing the screening process for trans blood donors nationally, we can ensure their eligibility assessment is the same no matter where they donate with Canadian Blood Services.

Frequently asked questions


What evidence are the criteria based on? 

Unfortunately, there have been few studies on the trans population in Canada. The Centres for Disease Control and Prevention’s (CDC) “HIV Among Transgender People” (April 2016), which summarizes information from the U.S. and European countries, states that studies reveal HIV prevalence rates of 22 per cent to 28 per cent among trans women in the U.S. and other high-income countries.

How do the criteria compare to the U.S.? 

To our knowledge, there are no uniform criteria in place in the U.S. However, based on our correspondence with medical directors at several large U.S. blood collection organizations, many are currently using sex assigned at birth to determine donor eligibility. Their concerns are similar to Canadian Blood Services’ in terms of the risks of TRALI, particularly for trans men, and HIV, particularly for trans women. 

How will trans donors who have not had gender affirming surgery be impacted?

Donors who have not had lower gender affirming surgery will be asked questions based on their sex assigned at birth. They will be eligible to donate or be deferred based on these criteria. For example, trans women, who have not had lower gender affirming surgery, will be asked if they have had had sex with a man in the last three months. If the response is yes, they will be deferred for three months after their last sexual contact with a man. 

What consultations have taken place within the LGBTQ community? 

Over the past several years, we were fortunate to receive input from the LGBTQ community to help inform our application to Health Canada to change the blood donation eligibility criteria for men who have sex with men (MSM). We consulted widely and in a variety of ways, including webinars, phone conversations and face-to-face meetings.  Our consultations have included LGBTQ representatives as well as representatives of patient groups who receive large amounts of blood products.  

We have heard from some people in the trans and gender non-binary community that our screening processes should change. We would also like to do better. We are committed to working with the trans and gender non-binary community to improve how we interact with donors.  Among other regular contact points, we have held face-to-face consultation meetings in Vancouver and in Toronto. To learn more, read the summary report from those consultations.  

Our guiding principles for all stakeholder engagement are to: 

  • Build supportive and constructive relationships with stakeholders. 
  • Engage stakeholders proactively and explore expectations. 
  • Inform good decision-making with evidence from different sources. 
  • Foster transparency in decision-making while respecting privacy and partnerships.
