The The American Red Cross in Manchester has issued an appeal for blood donation in Northern New England. There are specific blood types that the Red Cross needs right now. Over the past eleven weeks, donations have fallen 8 percent. Donors are being asked to sign up right now to prevent an urgent shortage of blood.

Donors with type O, B negative and A negative blood are especially needed.
