The method may include drawing whole blood into a centrifuge from a donor; spinning the centrifuge to cause centrifugal force to act on the whole blood to separate the whole blood into a least a first blood component and a third blood component; separating a first blood component from the whole blood; extracting the first blood component into a container; detecting when a second blood component is being extracted; and after the second blood component is detected and while the centrifuge continues to spin, forcing the separated first blood component back towards the centrifuge to move at least the third blood component from the centrifuge and back into the donor. The whole blood may then be centrifuged to collect only the desired blood component(s) (e.g., plasma) returning all other blood components to the donor during the same donation connection or cycle. For example, the apheresis method may extract whole blood from a donor while the donor is connected to the specialized apheresis machine. In at least one example embodiment, the method may further include attaching a second end of the fluid line loop to a rotationally fixed point of an apheresis machine and rotating (for example, via a rotor and motor assembly of the apheresis machine) the centrifuge assembly about the rotation axis relative to the rotationally fixed point of the apheresis machine.
