TUESDAY, July 22, 2014 (HealthDay News) -- Blood donations to the American Red Cross are down substantially, and the agency says an "emergency situation" could arise within weeks.
"Donations through the Red Cross are down approximately 8 percent over the last 11 weeks, resulting in about 80,000 fewer donations than expected," the agency said in a statement released Tuesday. "The number of donors continues to decline."
The looming blood shortage can be blamed, in part, on the calendar: This year, July Fourth fell on a Friday, cutting the number of blood drives the Red Cross could schedule for early July as volunteers went on vacation.
"In an average summer week, about 4,400 Red Cross blood drives are scheduled, compared to Independence Day week when only 3,450 drives occurred," the agency said.
While "all eligible donors" are being urged to give blood, types O negative, B negative and A negative are especially needed, the Red Cross said. Type O is the "universal" blood type, which can be safely used by anyone needing a transfusion.
Also needed are platelets, which allow blood to clot and are often needed by cancer patients, bone marrow recipients and burn victims. These patients need to be given these platelets within five days of donation, so it's essential that a fresh supply of donated platelets always be on hand, the Red Cross said.
The agency reminds Americans that blood can be safely donated every 56 days, and platelets can be donated as often as once a week.
Those deemed eligible to donate blood typically include anyone age 17 or older who weighs at least 110 pounds and is in generally good health. High school students and others aged 18 or younger also have to meet certain height and weight measurements.
"Blood and platelet donations are needed now and for the rest of the summer," the Red Cross said. "Individuals who donated blood earlier this summer may now be eligible to donate again and help patients
