The American Red Cross issued an emergency request for platelet and blood donors of all blood types to roll up a sleeve and give because fewer donations than expected were received in June and the first week of July.Warren County residents are urged to donate blood today, July 10, from 1:30 to 5:30 p.m. at McMinnville Civic Center.“Every two seconds, someone in the U.S. needs blood,” said Tim Ryerson, CEO for the American Red Cross Tennessee Valley Blood Services Region. “Each day donations come up short, less blood is available for these patients in need.”Nationwide, donations through the Red Cross were down approximately 10 percent in June, resulting in about 50,000 fewer donations than expected. The shortfall is similar to what the Red Cross experienced in June 2012.June can be among the most challenging months for blood and platelet donations as regular donors delay giving while they adjust to summer schedules.
