The present invention provides methods and systems to combine the capabilities of a hematology analyzer with those of a flow cytometer to yield a far more powerful analytical system than either device alone. In one embodiment, a method of analyzing a cell sample includes receiving a first data generated by an analysis of a first aliquot of the sample on a first particle analyzer having a fluorescence measurement device such as a flow cytometer, detecting at least one unresolved cell population in the first data, and accessing a second data stored on a storage device wherein the second data was previously generated by interrogating a second aliquot of the sample using at least one of a cell volume measurement device and a cell conductivity measurement device in a second particle analyzer such as a hematology analyzer. The unresolved cell population in the first data is then resolved using the second data. Corresponding system embodiments are also disclosed.

Cross-instrument method and system for cell population discrimination

In accordance with the principles of the invention, methods, systems, and computer-readable mediums are provided for displaying cellular analysis result data including accessing cellular analysis result data, accessing data of at least one template, and displaying the cellular analysis result data and the data of at least one template by overlaying the cellular analysis result data and the data of the at least one template, wherein the cellular analysis result data is displayed using different display attributes from the displayed data of the at least one template.

Displaying cellular analysis result data using a template

A method of producing low hemoglobin concentration cell percentage (LHCC %) and the method of use for detection of iron deficiency have been disclosed. LHCC % is a sigmoid function of mean cell hemoglobin concentration (MCHC), which correlates linearly with hypochromic red cell percentage.

Low hemoglobin concentration cell percentage and method of use in detection of iron deficiency

Methods are provided for measurement of nucleated red blood cells in a blood sample. The methods include exposing a blood cell sample to a reagent system to lyse mature red blood cells, subsequently analyzing nucleated red blood cells in a flow cell by axial light loss, DC impedance, and medium angle light scatter measurements; by axial light loss, low angle light scatter, and medium angle light scatter measurements; or by axial light loss, DC impedance, low angle light scatter, and medium angle light scatter measurements; and then differentiating nucleated red blood cells from other cell types by using measured signals and/or functions thereof.

Method of measurement of nucleated red blood cells

Methods are provided for measurement of nucleated red blood cells. The methods include exposing a blood cell sample to a reagent system to lyse mature red blood cells, subsequently analyzing nucleated red blood cells in a flow cell by axial light loss, low angle light scatter and DC impedance measurements, or two selected measurements thereof; and then differentiating nucleated red blood cells from other cell types by using measured signals and/or functions thereof.
