The American Red Cross of Greater Pennsylvania is asking donors to give blood or platelets in the remaining weeks of 2024.

Donors with type O negative blood and those giving platelets are especially urged to give now so patients can receive care they need in the coming weeks.

“This is a busy time for many. In addition to travel, seasonal illness and the threat of winter weather can also lead to lower appointment numbers and decreased donor turnout, making it tougher to keep the blood supply stable. Those who give regularly and those looking to give for the first time are encouraged to take one hour this December to help save lives with a blood or platelet donation,” American Red Cross said in a news release.

The Red Cross said anyone who donate through Jan. 3 will receive an exclusive Red Cross long-sleeved T-shirt, while supplies last. As an extra thank you to donors, those who give from Jan. 1 to 26, during National Blood Donor Month, will be automatically entered for a chance to win a trip for two to Super Bowl LIX in New Orleans. Details are available on the American Red Cross website.
