发明名称 Cross-instrument method and system for cell population discrimination
摘要 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.

主权项 1. A method of analyzing cell populations in a blood cell suspension sample, the method comprising: (a) obtaining first data, wherein the first data are generated by an analysis of a first aliquot of the sample using a fluorescence flow cytometer; (b) analyzing the first data to determine cell populations which are distinguishable from other cell populations as resolved cell populations in the first data, and detecting, using a processor in communication with the fluorescence flow cytometer, at least one unresolved cell population in the first data, wherein the first data includes a cell population of at least one of a first cell type and a second cell type, wherein there is substantial overlap in location of the first cell type and the second cell type in a plot of the first data; (c) obtaining second data, wherein the second data comprises at least one of a cell volume measurement, a cell conductivity measurement, and at least a first light scatter measurement, wherein the second data are generated by interrogating a second aliquot of the sample using a hematological particle analyzer; (d) analyzing the second data using the processor, in communication with the hematological particle analyzer, to determine a cell type present in the sample based on a signature pattern in a plot of the second data, wherein the determined cell type is one of the first cell type and the second cell type; and (e) enumerating the determined cell type from step (d) in the sample based on the first data, wherein the determined cell type cannot be accurately enumerated with flow cytometry data or hematology data alone.
