According the the American Red Cross, their supply of type O negative blood has dropped to critically low levels. Type O negative blood is always in high demand because it can be transfused to patients with any blood type, especially in emergency situations. Type O negative donors are needed now to help prevent the blood supply from declining further.
Eligible volunteer blood donors are asked to call 1-800-RED CROSS (1-800-733-2767) or visit redcrossblood.org to to make appointments.
A shortage of type O negative blood often occurs during the summer months when fewer donors are giving because of summer vacations and schools approaching summer break are hosting fewer drives.
Individuals who are 17 years of age , meet weight and height requirements (110 pounds or more, depending on their height) and are in generally good health may be eligible to give blood.
