Since announcing a national blood and platelet shortage a month ago, thousands of donors across the country have rolled up a sleeve to help rebuild the American Red Cross blood and platelet supply. As that generosity continues, the Red Cross is working around-the-clock to ensure patients have access to lifesaving transfusions and must collect 10,000 additional blood and platelet donations — over and above expectations — each week over the next month to sufficiently meet hospital needs. Donors of all blood types are urged to book a time to give now, especially those with type O blood or those giving platelets.
