Texans urged to donate blood in July to fight O positive drought

DALLAS-FORT WORTH – July 2, 2024 – With the O positive blood supply at critical levels, Texas-based Carter BloodCare is encouraging donors to lend an arm to help.

While all blood types are essential, recent O positive donations have not kept pace with patient needs.

Critical status means there is less than a day’s supply of blood on hand. This has led to surgeries and medical treatments getting delayed until the community supply is replenished.

At least 39% of the U.S. population is type O positive, making it the most common blood type. O positive is used in treating traumatic bleeding — often due to life-threatening traffic accidents — and in other medical emergencies.

Though it takes only one hour to give, blood donations typically drop during the summer as student donors go on break, an important point since 25% of the community blood supply is collected through high school blood drives. Also, as more people travel out of town for summer vacations, blood donations can drop.
