    • A method and an apparatus for enumerating one or more specific elements within a biologic fluid sample are provided. An embodiment of the method includes the steps of: a) providing a chamber formed between a first planar member that is transparent and a second planar member, which members are separated from one another by a substantially uniform height; b) introducing the biologic fluid sample into the chamber, wherein the chamber height is sized such that the sample extends between the first and second members, and sized relative to the specific elements within the sample such that the specific elements non-uniformly distribute within the sample upon introduction into the chamber; c) examining substantially all of the sample within the chamber and enumerating all of at least one of the specific elements; d) determining the volume of sample contained within the chamber; and e) determining the number of the at least one of the specific elements per unit volume.
    • 提供了用于列举生物液体样品中的一个或多个特定元件的方法和装置。 该方法的一个实施例包括以下步骤:a)提供形成在透明的第一平面构件和第二平面构件之间的室,该构件通过基本均匀的高度彼此分离; b)将生物流体样品引入室中,其中室高度的大小使得样品在第一和第二构件之间延伸并且相对于样品中的特定元件的尺寸,使得特定元件不均匀地分布在 样品进入室内; c)基本上检查所述室内的所有样品并列举所述至少一个所述特定元件; d)确定容纳在室内的样品的体积; 以及e)确定每单位体积中的至少一个特定元素的数量。

    • The inventions relates to compositions and method for determining the absolute counts of cells per unit volume of a sample. Such a method comprises: (a) providing a container containing: (i) a predetermined quantity of microparticles; and (ii) a cell-binding agent; in which the microparticles are disposed in or on a matrix which adheres to at least one wall of the container such that substantially all the microparticles are thereby attached to the container; (b) adding a known volume of sample to the container; (c) determining the ratio of microparticles to cells by counting microparticles and cells in a volume of the sample; and (d) determining the absolute count of cells by multiplying the number of cells per microparticle by the concentration of microparticles in the sample. Preferably, the matrix retains substantially all the microparticles in or on the container during routine handling, including inversion, of the container, in the absence of mechanical retaining means such as a retainer grid in the container.
    • 本发明涉及用于确定每单位体积样品的细胞绝对计数的组合物和方法。 这种方法包括:(a)提供容器,该容器包含:(i)预定量的微粒; 和(ii)细胞结合剂; 其中微粒设置在附着于容器的至少一个壁的基质中或基质上,使得基本上所有的微粒由此附着到容器上; (b)向容器中加入已知体积的样品; (c)通过对一定体积的样品中的微粒和细胞进行计数来确定微粒与细胞的比例; 和(d)通过将每个微粒的细胞数乘以样品中微粒的浓度来确定细胞的绝对计数。 优选地,在不存在诸如容器中的保持器栅格的机械保持装置的情况下,在常规处理(包括反转)期间,基体将基本上全部微粒保留在容器中或容器上。
