OneMatch Maps the Route to a Bone-Marrow Registry

Field notes

Each country entry compresses the practical details of donor enrollment into a small checklist: registry name, method, age range, and expected effort. The visible examples distinguish home kits, online registration, blood-donation enrollment, and official pre-registration rather than treating every country alike. Some constraints are unusually concrete, including Japan’s 2 mL blood sample, Colombia’s ten-minute estimate, and Hungary’s note that registration can occur within 56 days after blood donation.
