  • Method for flagging a sample
    Patent number: 8911669
    Abstract: A hematology analyzer is provided. In certain embodiments, the hematology analyzer comprises: a) a flow cell; b) a light source for directing light to the flow cell; c) a plurality of detectors for detecting a plurality of optical characteristics of a blood cell passing through the flow cell; and d) a data analysis workstation programmed to: i. enumerate test blood cells passing through the flow cell; and ii. flag a blood sample as containing lysis-resistant red blood cells or fragile white blood cells.
    Type: Grant
    Filed: August 24, 2009
    Date of Patent: December 16, 2014
    Assignee: Abbott Laboratories

  • Method for determining volume and hemoglobin content of individual red blood cells
    Patent number: 8906308
    Abstract: A method for determining the volume or hemoglobin content of an individual red blood cell in a sample containing a population of red blood cells. The method may be performed on a hematology analyzer. Also provided are a hematology analyzer for performing the method and a computer-readable medium containing programming for performing the method.

  • Method for determination of nucleated red blood cells and leukocytes in a whole blood sample in an automated hematology analyzer
    Patent number: 7674622
    Abstract: A method for enumerating white blood cells and nucleated red blood cells. The steps of the method are as follows: (a) providing a lysed sample of whole blood; (b) introducing the lysed sample to a light-scattering multi-angle depolarizing flow cytometer; (c) removing depolarizing interference, e.g., lipid droplets and other measured particles; (d) differentiating nucleated red blood cells and noise from white blood cells in the absence of depolarizing interference; (e) differentiating nucleated red blood cells from noise in the absence of depolarizing interference and white blood cells; and (f) differentiating possible platelet clumps.
