The American Red Cross continues to see a concerning trend - blood donations are being sent to hospitals faster than they are coming in.

The Red Cross has collected about 50,000 fewer blood donations than needed over the last two months. Donors are asked to make an appointment to give blood or platelets now to avoid a looming blood shortage.

To help head off a more serious situation, the Red Cross is teaming up with Warner Bros. Discovery for the 35th anniversary of Shark Week and the theatrical release of Meg 2: The Trench. The public is encouraged to celebrate a summer of sharks and help shore up the national blood supply by giving in July.

In thanks for helping, the Red Cross is offering several incentives to donors who come out to give blood or platelets in the coming weeks. Additionally, in response to the great need for blood, those who by coming to give through July 16 will receive a limited-time bonus $15 gift card by email to a merchant of their choice.

In addition, those who give between July 12 and 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. Details are available at RedCrossBlood.org/Shark.

By scheduling and keeping appointments in July, donors can help provide for those in immediate need of lifesaving care.

To schedule an appointment to donate, download the Red Cross Blood Donor App, visit RedCrossBlood.org or call 1-800-RED CROSS (1-800-733-2767).

A blood donor card or driver’s license or two other forms of identification are required at check-in. Individuals who are 17 years of age in most states (16 with parental consent where allowed by state law), weigh at least 110 pounds and are in generally good health may be eligible to donate blood. High school students and other donors 18 years of age and younger also have to meet certain height and weight requirements.
