Abstract:
1. A method for assessing prospective transfusion efficacy of red blood cells, comprising: subjecting a sample containing red blood cells to a controlled physical stress, said stress being applied at one or more combination(s) of intensity and predetermined duration causing hemolysis of at least a portion of said cells; evaluating optically said hemolysis to create one or more data point(s) corresponding to said one or more combination(s) of intensity and predetermined duration, whereby each data point reflects what fraction of cells became hemolysed upon having the stress applied for a given predetermined duration at a given intensity; and generating an at least partially age-independent numerical value(s) representing red blood cell suitability for transfusion, said numerical value(s) being based wholly or partially on said one or more data point(s).
