Abstract: A pipette tip includes a main body having an upper end, a lower end and a sidewall extending between the two ends. A bore extends axially through the main body between the upper and lower ends. The lower end has a bottom surf ace in which is formed a central opening that communicates with the axial bo re to allow the passage of fluid therethrough. The bottom surface is formed with at least one groove that may be concentrically disposed or spirally dis posed about the central opening. The at least one groove acts to inhibit flu id passing through the central opening from at least partially flowing along the outer surface of the sidewall from the central opening toward the upper end of the main body of the pipette tip.

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 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: A method to track stability and performance of diagnostic instrumentation, especially for veterinary automated hematology analyzers, applies a weighted moving averages algorithm to the diagnostic results of patient samples calculated by the analyzer. Control chart rules are used to set limits 5 or ranges in order to determine if weighted averaged diagnostic results are within or outside of such limits or ranges. If the weighted average diagnostic results are outside of such control chart rule limits, then fuzzy logic and a gradient descent algorithm are applied to the weighted averaged diagnostic results.
