Information

Quick Overview: Dedicated registry for donors with rare antigen combinations beyond the standard ABO/Rh system.

Process Duration: Standard whole blood or apheresis timeframe depending on requisition.

Donation Frequency: As needed for matched patient requisitions (or standard donation schedules).

Impact: Provides compatible matches for patients with rare blood phenotypes or complex antibody profiles.

Key Details:

• Beyond ABO: Covers rare sub-types (e.g., Kell-negative, Duffy-negative, Bombay phenotype, rare Rh variants like r''r').

• The Challenge: Patients with rare blood groups often develop antibodies against common blood antigens after multiple transfusions.

• Platform Purpose: Creates an active network so rare patients do not face critical delays searching for matched blood.
