摘要:
Container identification data from a container inspection unit that analyzes a container containing a liquid is combined with liquid level detection raw data from a liquid level detection unit that analyzes the container containing the liquid and a liquid level detection result is generated. The liquid level detection result is cross-checked with additional data from the container inspection unit. The result can be used to plan a route for the container in the laboratory automation system.
摘要:
Embodiments of the present invention encompass automated systems and methods for analyzing platelet parameters in an individual based on a biological sample obtained from blood of the individual. Exemplary techniques involve correlating aspects of direct current (DC) impedance and/or light measurement data obtained from the biological sample with an evaluation of platelet conditions in the individual.

A method of correction of particle interference to hemoglobin measurement of a blood sample on a hematology analyzer is provided. The method includes mixing an aliquot of a blood sample with a lytic reagent to lyse red blood cells and forming a sample mixture; measuring absorbance of the sample mixture at a predetermined wavelength of a hemoglobin chromogen formed in the sample mixture, and obtaining an apparent hemoglobin concentration of the blood sample using obtained absorbance; measuring concentration and size of cellular particles remaining in the sample mixture; removing contribution of the cellular particles to the apparent hemoglobin concentration using the concentration and the size of the cellular particles to obtain a corrected hemoglobin concentration of the blood sample; and reporting the corrected hemoglobin concentration of the blood sample.
摘要:
Systems and methods for non-linear histogram segmentation for particle analysis are provided. In one embodiment, a method for analyzing particles comprises creating an initial two-dimensional histogram based on two selected parameters of the particles, filtering the initial two-dimensional histogram to generate a filtered two-dimensional image, detecting a plurality of seed populations in the filtered two-dimensional image, generating one or more linear contour lines, each having a plurality of contour points, to separate the detected seed populations, and adjusting the contour points in at least one of the linear contour lines to separate the detected seed populations.
