Blood donation
KLOS has sponsored a blood drive in conjunction with the American Red Cross annually since 1982. Blood donation centers are set up throughout the station's listening area for several days, usually in the summer months when donation levels are typically low. In 2014, the blood drive collected approximately 7,900 units of whole blood, which can be separated into red blood cells and plasma. As a token of gratitude, the station has given donors rewards such as T-shirts and vouchers toward concert tickets.
