Patent number: 8148101Abstract: A method for distinguishing erythroblasts from bacteria by automated hematology analyzers, such as, for example, the CELL-DYN® 4000 automated hematology analyzer and the CELL-DYN® Sapphire™ automated hematology analyzer. Bacterial cells scatter light and fluoresce differently than do red blood cells, white blood cells, erythroblast nuclei, and platelets. Signals generated by bacteria are distinguishable from those of erythroblasts because the signals generated by erythroblast nuclei are sufficiently unique that erythroblast nuclei can be distinguished from signals generated by bacteria. Signals generated by platelets, lysed red blood cell ghosts, and other cell debris are blocked by the triple-trigger circuitry of the hematology analyzer, because all of the signals generated by noise are below the AND/OR thresholds.Type: GrantFiled: July 22, 2008Date of Patent: April 3, 2012Assignee: Abbott LaboratoriesInventors: Young Ran Kim, Willie J. Cowart
