Abstract
Blood processing systems and methods employ two sensors, one to detect a condition of plasma exiting a separation device and another sensor to detect a condition of a cellular component exiting the separation device. The first sensor detects, e.g., contamination of the plasma due to presence of unwanted cellular components. The second sensor detects, e.g., dilution of the cellular component due to presence of plasma. Blood processing parameters are carried out based, at least in part, by conditions detected by one or both of the sensors.
