Wait times may vary by country or specific donation type (e.g., Double Red, Plasma). This uses the standard 56-day whole blood rule.
How This is Calculated
Whole blood donation eligibility follows the standard 56-day (8-week) waiting period between donations, as established by the American Red Cross and AABB (formerly the American Association of Blood Banks). Platelet donations require a 7-day wait; double-red-cell donations require 112 days.
