A centrifugal blood processing apparatus comprising a centrifuge rotor, a separation chamber, a tubing set for conducting blood components and fluids and having an inlet line, and an outlet line. Apparatus tests flow conditions using a red light-green light sensor to detect non-recoverable hemolysis during priming by identifying a high R/G ratio, preferably a ratio of greater than or equal to fifty (50), prior to the beginning of the first return of blood components to a donor followed by identifying a R/G ratio at least as great as one and one tenth (1.1) together with a green signal less than a predetermined value, preferably less than or equal to one thousand (1000) reflectance units. If these conditions are detected, an alarm is given and the apheresis procedure is discontinued. |
