The American Red Cross has a significant need for type O negative blood donors to donate blood for patients, according to a press release.

Type O negative blood can be transfused to patients with any blood type and is often used in emergency situations. While less than seven percent of the U.S. population has type O negative blood, hospitals depend on frequent O negative donations to ensure it’s always available for patients in need.

Eligible donors with type O negative blood are encouraged to make a whole blood or double red cell donation, where available, through the Red Cross. During a double red cell donation, two units of red blood cells are collected while most of the plasma and platelets are returned to the donor.

“Type O negative donors are an important part of the Red Cross trauma team,” said Sue Thesenga, communications manager for North Central Blood Services.

“While all blood types are needed, type O negative donations are necessary in emergency situations when there is no time to determine a patient’s blood type. Because there is such a high demand for type O negative blood, O negative donors are needed to donate often.”

Blood donation appointments can be quickly and easily scheduled by using the Red Cross Blood Donor App, visiting redcrossblood.org or calling 1-800-RED CROSS.

The Red Cross must collect approximately 14,000 blood and platelet donations every day for the patients at about 2,600 hospitals and transfusion centers nationwide. Blood and platelets are needed to respond to patient emergencies, including accident and burn victims, heart surgery and organ transplant patients, and those receiving treatment for leukemia, cancer or sickle cell disease.

Those who come to donate now through May 15 will be entered to win four single-day tickets to any of 10 Cedar Fair theme parks in the United States For a full list of participating parks, visit redcross.cedarfair.com.
