Abstract: Disclosed are approaches for analyzing a two-dimensional (2D) dot plot, without human intervention, to identify conditions in a hematology sample. The analyses operate to provide indications of left shift and/or small-pathologic red blood cells based on spatial distribution of one or more groups of dots in the 2D dot plot. Spatial distribution of a group of white blood cell dots is analyzed to provide an indication of left shift. Spatial distribution of a group of red blood cell dots is analyzed to provide an indication of presence of small-pathologic red blood cells.

Abstract: A method for detecting bacteria and determining the concentration thereof in a liquid sample includes the steps of taking an optical section through a container holding a volume of the liquid sample at a predetermined field of view and at a predetermined focal plane depth or angle and after a period of time has elapsed to allow non-bacteria in the sample to settle to the bottom of the container. Since bacteria auto arranges in the liquid sample, forming a lattice-like grid pattern, an optical section through the volume of auto-arranged bacteria may be used to measure the quantity of bacteria residing in that section. A container for holding the liquid sample has particular structure which aids in separating the non-bacteria from the bacteria.

Abstract translation: 用于检测细菌并确定其在液体样品中的浓度的方法包括以下步骤：将光学部分通过容纳液体样品体积的容器在预定视场和预定焦平面深度或角度处， 一段时间已经过去，以使样品中的非细菌沉淀到容器的底部。 由于细菌自动排列在液体样品中，形成格子状格栅图案，所以可以使用通过自动排列的细菌体积的光学部分来测量该部分中存在的细菌的数量。 用于保持液体样品的容器具有有助于将非细菌与细菌分离的特殊结构。

Abstract: The present disclosure relates to quality control for point-of-care medical diagnostic systems. In various embodiments, the system includes an on-board storage containing a synthetic quality control material, a plurality of sub-systems having a plurality of operating parameters and including a material analyzer, a database storing quality control results that include results of the material analyzer analyzing the synthetic quality control material over time, one or more processors, and at least one memory storing instructions which, when executed by the one or more processors, cause the system to, automatically without user intervention: generate a control chart based on the quality control results, determine that a parameter of the plurality of operating parameters is out-of-tolerance based on the control chart, and adjust at least one of the plurality of sub-systems without user intervention to bring the out-of-tolerance parameter to within tolerance.

Abstract: A method for determining the density of particles includes passing a carrier fluid and particles through a fractionation cell at a predetermined rate, where the carrier fluid has a predetermined density, the fractionation cell has a housing including a first axial end and a second axial end and the fractionation cell defines an interior carrier fluid flow-through channel, and an upper fluid outlet and a lower fluid outlet positioned below the upper fluid outlet, passing the carrier fluid and the particles through the upper fluid outlet and the lower fluid outlet, measuring a first concentration of particles passing through the upper fluid outlet, measuring a second concentration of particles passing through the lower fluid outlet, and determining a density of the particles based at least in part on the first concentration and the second concentration of particles.
