The American Red Cross urgently needs blood and platelet donors to make an appointment now to give and help ensure patients can get the treatment they need at a moment’s notice.

Now is an important time to give blood and platelets. A seasonal decline in donations occurs from Thanksgiving to New Year’s Day when donors get busy with family gatherings and travel. In addition, severe winter weather can cause blood drive cancellations and negatively affect the blood supply. Patients like McMahon can’t afford for there to be a shortage of blood.

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

As a special thank-you for helping meet the urgent need, those who come to give Dec. 20 through Jan. 6 will receive a long-sleeved Red Cross T-shirt, while supplies last.
