The present disclosure describes an apparatus and associated method for quantifying the quality degradation of individual stored red blood cell (RBC) units, thereby yielding information to improve decisions regarding their respective allocation, patient suitability, and use. This apparatus and the methods of its use are amenable to clinical implementation as well as indicative of any given unit's relative viability and thus prospective efficacy. This would provide clinicians with actual data on RBC quality when making decisions about which and how many units to use for transfusion of a given patient. Moreover, deploying this testing throughout the supply chain will improve distribution, planning, and inventory control decisions. A vital aspect of this testing system is the accumulation of copious output and other associated data and the mathematical analyses thereof to optimize algorithms by which to characterize each subsequent test output as meaningfully as possible. While the present invention is directed toward applications in blood quality control, the core technology of “quantifying RBC fragility via stress-induced hemolysis and subsequent optical and computational analysis” could have broader application, such as in disease diagnosis. The apparatus for quantifying the quality degradation of individual stored (RBC) units comprises: a hemolysis unit; an optical analysis unit; and a computation unit. Similarly, the associated process for quantifying the quality degradation of individual stored (RBC) units comprises: a hemolysis step; an optical analysis step; and a computation step.
