Abstract
Blood separation methods are provided for mid-processing calculation of blood composition. Blood is conveyed into a device having an outlet line and the device is spun to separate platelets from the blood. A flow of platelets is conveyed from the device by the outlet line and the platelets in the outlet line are optically measured. With said optical measurement, a current platelet yield, a platelet pre-count, the volume of blood to process to collect a target amount of platelets, and/or the processing time required to collect a target amount of platelets is calculated. The optical measurement can also be used to calculate an amount of storage fluid to convey into a collection container with the platelets.
