World First: KFSH Jeddah's Single-Session Stem Cell Protocol Sets a New Global Standard Balancing Donor Safety and Treatment Efficiency

JEDDAH, Kingdom of Saudi Arabia, July 8 (Bernama) -- King Faisal Specialist Hospital and Research Centre in Jeddah has successfully developed and implemented the world’s first protocol of its kind, using an algorithm to accurately estimate the expected stem cell yield from each donor. The protocol enabled stem cell collection to be completed in the first session for 100% of male donors and 94.9% of all donors, while eliminating the need for third and fourth collection sessions altogether.

The protocol is designed to limit repeat collection sessions and the risks they can pose to donor safety. Figures from the U.S. National Marrow Donor Program show that repeat sessions raise a donor’s likelihood of being hospitalized for recovery sixfold. By reducing how often sessions must be repeated, the protocol addresses that risk directly and sets a new global benchmark that bal ances donor safety with treatment efficiency.
