Spain’s Marrow Donor Registry Expands: Andalucía Tops 118,000 Active Donors, Madrid Reaches 72,213

Operational upgrades are improving transplant logistics to support a broader, more diverse donor base.

Overview

  • Andalucía reports more than 2,000 new REDMO registrations in 2025, including 116 from Córdoba, for a total of 118,771 active donors and nearly 300 pending confirmations.
  • Madrid counts 72,213 registered donors, a 6.5% rise over 12 months with 4,670 additions, and reports 178 effective donations in the last year.
  • Only 25% to 30% of patients find a compatible unrelated donor, underscoring the call for continued recruitment and greater demographic diversity.
  • Average unrelated-donor searches now take about 27 days, supported by higher-quality HLA typing in Málaga and a REDMO certification card integrated into Madrid’s virtual health record.
  • Most donations are collected via peripheral blood (85%), with 15% requiring operating-room extraction, according to regional transfusion authorities.
