The invention relates to a method and a blood bag system for the separation of blood components from whole blood, the blood being tapped into a blood bag, which is then centrifugated to form an upper layer containing blood plasma, a lower layer containing red blood cells and an intermediate buffy coat layer, and it is characterized in that the blood is tapped into a first blood bag (1,28) having outlets both at the top (7,30) and at the bottom (1,33), and that after centrifugation the layer containing blood plasma is pressed out through the upper outlet (7,30) of the blood bag while the layer containing red blood cells is pressed out through the lower outlet port (10,33) of the blood bag, so that substantially only the intermediate layer remains in the bag (1,28).

A method of separating blood components contained in a blood sample, comprising the steps of: (a) providing a primary blood bag for receiving the blood sample; (b) providing at least two transfer blood bags and at least two conduits, a first of said at least two conduits connecting said primary bag

A method of separating blood components contained in a blood sample, comprising the steps of: (a) providing a primary blood bag for receiving the blood sample; (b) providing at least two transfer blood bags and at least two conduits, a first of said at least two conduits connecting said primary bag with a first of said at least two transfer blood bags and a second of said at least two conduits connecting said primary bag with a second of said at least two transfer blood bags; (c) collecting a blood sample in the primary blood bag having at least one top portion outlet connecting with the first of said at least two conduits and at least one bottom portion outlet connecting with the second of said at least two conduits; (d) centrifugating said primary blood bag and said transfer blood bags for separating said blood sample into an upper layer containing blood plasma, a lower layer containing red blood cells, and an intermediate layer containing white blood cells; and (e) squeezing said primary bag while said intermediate layer is in fluid contact with each of said upper and lower layers in said primary bag to thereby cause said upper layer to transfer from said primary bag through said at least one top portion outlet and the first of said at least two conduits to said first transfer bag and said lower layer to transfer from said primary bag through said at least one bottom portion outlet and the second of said at least two conduits to said second transfer bag so as to leave essentially only said intermediate layer in said primary blood bag.
