What Are The Major Drivers Supporting The Human Leukocyte Antigen (HLA) Antibody Screening Market Growth?
The rising organ transplantation rates are expected to propel the growth of the HLA antibody screening market going forward. Organ transplantation rates refer to the number of organ transplant procedures performed within a specific population and time, typically expressed per year or per million people. The rise in transplantation procedures is largely attributed to the increasing burden of chronic and end-stage diseases, as more patients advance to organ failure, the demand for organ replacement therapies correspondingly increases. HLA antibody screening supports higher organ transplantation success by ensuring better donor-recipient matching before surgery, thereby lowering the likelihood of immune-mediated rejection that reduces graft loss and complications, improving long-term transplant outcomes, and enabling more effective use of available donor organs. For instance, in January 2025, according to the Health Resources and Services Administration, a US-based Department of Health and Human Services agency, lung transplants experienced the highest proportional increase between 2023 and 2024, rising from 3,026 procedures to 3,340, which represents a 10.4% growth. Therefore, the rising organ transplantation rates are driving the growth of the HLA antibody screening market.
