The Kentucky Blood Center has issued an urgent request for negative blood types.
People with O-negative, B-negative and A-negative blood types are being asked to donate, according to a blood center news release.
Blood center spokeswoman Denise Fields said the amount of blood used for transfusions fluctuates monthly, and it happened to increase in July.
The negative blood types are being distributed to hospitals almost as quickly as they are being donated, she said.
