Evaluation of Computational Models for Hemolysis Estimation

WebIn vivo hemolysis, also known as intravascular hemolysis or hemolytic anemia, is conventionally defined as a process of red blood cell (RBC) injury and disruption within the bloodstream, typically caused or triggered by a kaleidoscope of congenital or acquired conditions, as summarized in Table 1. WebClinical laboratories commonly encounter hemolyzed specimens which, if not managed appropriately, influence the reliability of patient results. Consequently, laboratories must have robust, systematic processes in place for identifying these samples and for consistently quantifying the degree of hemolysis.
