Community Blood Center of the Ozarks has issued a Code Yellow Alert, because they’re low on Type O Negative blood. The alert means the center has less than a two day supply of O- on hand in hospitals. If you want to donate, you need to be at least 110 pounds, be in good health and present the required identification. One blood donor can save the lives of up to three people. To donate, go to www.cbco.org or call 1-800-280-5337.
