Weekly Group O Blood Supply Report

The latest data from AABB’s weekly Group O blood supply report is available. Blood donations are needed to ensure blood availability. AABB encourages those who are eligible to donate blood or blood components regularly to ensure that this lifesaving resource is available for patients in need. 

The blood supply report uses the individual days of supply reported by America’s Blood Centers, the American Red Cross and Blood Centers of America to estimate the total labeled inventory collected by blood centers in the United States. The estimate is weighted using data from the Centers for Disease Control and Prevention’s National Blood Collection and Utilization Survey. Most hospital-based blood centers are not part of this analysis.

AABB will update this report every Tuesday afternoon. It is intended to complement AABB’s biweekly Blood Products Availability, which utilizes data from AABB’s National Blood Exchange to estimate the supply of red blood cells, platelets and frozen products.
