Stanford Blood Center calls for donations

Shaikh, a resident of Walnut Creek, decided to drive to the center and donate blood after reading news on Twitter about the blood center's urgent need for donations of type O negative and O positive blood to treat victims of the Asiana Airlines plane crash. The blood center received 71 units of blood on Monday when it usually receives about 45-50 on the same day. Photo by Veronica Weber.
