    摘要: A method and apparatus for automatically and rapidly, retrieving, counting and/or analyzing at least one selected white blood cell population and/or subset thereof of a whole blood sample or portion thereof. A volume of a biological sample containing the white blood cells is prepared and at least one reactant specific or preferential at least to some selected biological cells is introduced thereto and rapidly mixed for a short period of time. The opacity and/or volume parameter of the cells can be modified and the mixture is then counted and analyzed in one or more steps to obtain the desired white blood cell population analysis.The biological sample can be a whole blood sample and the reactant can include or be a lyse or a monoclonal antibody bound to microspheres, which will bind to specific ones of the cells or a combination of lyse and microspheres with antibody bound thereto. The microspheres can be magnetic and the bound cells can be magnetically removed for retrieving and analyzing the remaining blood cell population.

    摘要: A method and apparatus for performing screening of obscured or partially obscured cells to enumerate one or more cell population subsets. For example, a whole blood sample or portion thereof is screened to provide the desired analysis of one or more white blood cell population subsets in the sample. A white blood cell population including the obscured subset of interest is first counted, along with a standard population. The standard population can be one of the total number of white blood cell populations, a second white blood cell population which does not obscure the shifted or non-shifted sensed characteristic of the subset of interest, an artificial population formed by microspheres which also do not obscure the shifted or non-shifted sensed characteristic of the subset of interest or a white blood cell population into which the sensed characteristic of the subset will be wholly or partially shifted. The sensed characteristic of the white blood cell population subset of interest then is shifted by binding microspheres having monoclonal antibodies specific to the white blood cell population subset of interest to the cell population. The white blood cell population, and the standard population then are again counted and compared to the original counts to obtain an enumeration of the white blood cell population subset of interest.

    摘要: An optical screening method and apparatus for identifying both the morphology and selected characteristics or properties expressed by cells, such as cancer cells. The cells are combined with one or more different sets of microspheres, each set having a reactant bond thereto which will bind to a specific molecule which can exist on one or more types of cancer cells. The cells and microspheres are formed as a smear on a slide, stained with a histological type stain and optically viewed to identify the type of cells to which the different sets of microspheres do or do not bind. The different sets of microspheres are optically differentiated by having different optical characteristics, such as size, shape, color or combinations thereof. A fast cancer cell screening method or panel is provided by adding different sets of microspheres having different reactants bound thereto to different sample portions and optically screening the different sample smears. The microspheres also can be removed from a sample portion with any cells bound thereto and compared to another non-modified sample portion to ascertain if the cancer cells of interest have been removed from the sample portion.
