Abstract
A method and device are provided for centrifugally separating plasma from whole blood in which whole blood is introduced into a flow circuit having a blood access device connected to a first tubing for drawing whole blood from a blood source and for flowing whole blood to a centrifugal separation chamber; a volume of saline is added to the whole blood as it flows through the first tubing to dilute the whole blood; the volume of saline added to the whole blood is tracked; the whole blood having saline added thereto is separated in the centrifugal separation chamber so that an interface is created between the plasma and added saline and the cellular components of the whole blood; the separated plasma and added saline is flowed from the centrifugal separation chamber to a collection container; and a volume for the plasma and added saline in the collection container is determined.
