What actually makes someone a “match” for organ transplant? And how close are we to a future where transplant compatibility becomes even more personalized?In this episode of Living Transplant Podcast, host Candice sits down with Jeff Kiernan from UHN’s HLA Lab to explore the hidden world of transplant immunology — the science that helps determine donor compatibility, monitor antibodies, and support long-term transplant success.Jeff breaks down what HLA is, why the idea of a “perfect match” is often misunderstood in solid organ transplant, and how new innovations are helping highly sensitized patients access life-saving organs. From molecular matching and immune response prediction to the future of organ preservation and personalized transplant care, this conversation offers a fascinating behind-the-scenes look at the science shaping the future of transplantation.Candice also reflects on her own experience as a kidney transplant recipient and what it means to live with the realities of sensitization, second transplants, and long-term graft survival.Whether you’re a transplant recipient, donor, healthcare professional, or simply curious about the incredible science happening behind the scenes, this episode shines a light on the people and technology working every day to help patients live longer, healthier lives.In This Episode:What HLA actually means and why it mattersThe truth about “perfect matches” in organ transplantHow antibodies affect transplant compatibilityWhy highly sensitized patients face additional challengesThe future of molecular matching and predictive transplant scienceHow UHN teams collaborate across transplant programsInnovations in organ preservation and perfusion technologyThe behind-the-scenes role of Medical Laboratory Technologists (MLTs)Links How UHN’s Transplant Immunology Lab matches patients with donor organs, stem cells: https://www.uhn.ca/corporate/News/Pages/uhn-transplant-immunology-lab-hla-matching.aspx Learn more about living organ donation: www.livingorgandonation.ca Living Organ Donation at UHN: UHN Ajmera Transplant CentreInformation Sessions for potential donors: givelifeuhn.eventbrite.ca  Becoming a living donor: https://www.uhn.ca/Transplant/Pages/become_living_donor.aspxCBS Highly Sensitized Patient Program: https://professionaleducation.blood.ca/en/organs-and-tissues/programs/highly-sensitized-patient-hsp-program Each episode, we share patient stories about organ donation from transplant recipients and living donors, along with insights and education from leading medical experts.
