Abstract
Provided are a blood bag system and a blood treatment method capable of securely and efficiently obtaining a medium specific gravity blood component having a sufficiently low content rate of a light specific gravity blood component. In a blood bag system () used for a blood treatment method, in a transfer completed state in which whole blood in a first bag () is centrifuged to transfer blood plasma to a second bag () through a first transfer tube () and transfer red cell concentrates to a third bag () through a second transfer tube (), a buffy coat is left in the first bag (). In the transfer completed state, when a platelet added solution is transferred from a fourth bag () to the first bag () on which a centrifugal force acts through a third transfer tube (), blood plasma in the buffy coat is discharged from the first bag ().
