After a summer of declining donations, the American Red Cross needs the public's help to prevent a blood shortage.

When a donor makes and keeps an appointment to give blood or platelets in the weeks ahead, they can help ensure trauma patients, those undergoing cancer treatment and people with lifelong blood disorders can get the blood they count on.

Right now, the Red Cross especially needs type O negative, type O positive and type B negative blood donors, as well as platelet donors. Donors of all blood types can schedule an appointment to give by downloading the Red Cross Blood Donor App, visiting RedCrossBlood.org or calling 1-800-RED CROSS (1-800-733-2767).

The Red Cross is teaming up with Warner Bros. for the theatrical release of "Meg 2: The Trench" to celebrate a summer of sharks and help stave off a summer blood and platelet shortage. All who come to give through Aug. 12 will be automatically entered for a chance to win a three-night New York getaway for two with a private shark dive adventure at Long Island Aquarium. Those who come to give throughout the month of August will also get a $10 e-gift card to a movie merchant of their choice. Details are available at RedCrossBlood.org/Movie.

Amplify your impact − Volunteer

A stable blood and platelet supply is critical to national preparedness. Additionally, as we approach the beginning of what is expected to be another active hurricane season, the Red Cross urges everyone to get ready now and consider becoming a volunteer to help people affected by the growing number of climate-driven disasters.
