A blood separation device includes a pump system, a separator, and a controller. The controller is programmed to execute a blood separation procedure including a red blood cell collection stage in which blood is conveyed into the separator, red blood cells are separated from the blood in the separator, and the separated red blood cells are conveyed from the separator into a collection container. The red blood cell collection stage is ended when a target volume of blood has been separated in the separator. The controller then determines a percentage of the red blood cells from the target volume of blood that have been collected in the collection container based on the volume of red blood cells and the hematocrit of the fluid in the collection container, a volumetric flow rate of pure red blood cells in the blood conveyed into the separator, and the procedure time.

Systems and methods are provided for separating blood into two or more components for collection of red blood cells, plasma, or both red blood cells and plasma. A blood separation system includes a blood separation device and a fluid flow circuit configured to be mounted to the blood separation device. The blood separation device includes a centrifugal separator and a spinning membrane separator drive unit, with the blood being separated into its constituents by the centrifugal separator. Separated plasma may be collected following separation by the centrifugal separator or may first be conveyed from the centrifugal separator into the spinning membrane separator drive unit to separate cellular blood components from the plasma prior to collection of the filtered plasma. The cellular blood components filtered from the plasma may be retained in the circuit as a waste product or may be flushed out of the circuit to a recipient.
