Blood Centers of the Pacific was a community-based, nonprofit blood center collecting blood donations and provides safe blood and blood components for transfusion and also related services to more than 40 hospitals in the Bay Area and Northern California. Its predecessors included the first blood bank in the United States, which through expansions grew in the San Francisco and Sacramento areas. The Blood Centers of the Pacific name was retired in 2018 when parent Blood Systems, Inc., unified all of its regional operations under the Vitalant name.
