摘要： A centrifuge tube is used to hold a mixture of several constituents, and also contains a generally cylindrical float. The float settles, after centrifugation, into the zone occupied by the constituent whose volume is to be measured. The constituent layer will settle, after centrifugation, into the annular space between the tube bore and the outside of the float, and will be expanded axially due to the restricted volume of the annular space. The degree of expansion is dependent upon the respective sizes of the float O.D. and the tube bore ID, both of which must be closely controlled for accurate results. A known volume of a control material is placed in the tube to settle into the annular space during centrifugation in an area thereof outside of the constituent layer zone. The length of the band of the control material is measured after centrifugation and is compared to a known length which will result if the annular space is of the proper target volume. A correction factor is thus obtained and applied to all of the other constituent layers which were measured. The band thus forms a varying reference which reflects the actual volume of the annulus.

摘要翻译：离心管用于容纳几种成分的混合物，并且还包含一般为圆柱形的浮子。离心后，浮子沉降到被测量体积所占据的区域内。构成层在离心后将沉淀到管孔和浮体外部之间的环形空间中，并且由于环形空间的体积受限制而将轴向膨胀。膨胀程度取决于浮子O.D的各自尺寸。和管孔ID，两者都必须严格控制以获得准确的结果。将已知体积的对照材料放置在管中，以便在构成层区域外的区域中离心期间沉降到环形空间中。在离心后测量对照材料带的长度，并将其与已知的长度进行比较，如果环形空间具有适当的目标体积，则该长度将产生。因此获得校正因子并将其应用于所测量的所有其它构成层。因此，带形成变化的参考，其反映环的实际体积。

摘要： A patient's health may be diagnosed by centrifuging blood samples in a transparent tube, which tube contains one or more bodies or groups of bodies such as floats, inserts, liposomes, or plastic beads of different densities. Each density-defined body carries analyte-capture binding materials such as antigens or antibodies, which are specific to an epitope, or other specific high affinity binding site on a target analyte which target analyte may be in the blood or other sample being tested; and the level of which analyte is indicative of the patient's health. At least one labeled binding material which is also specific to an epitope, or other specific high affinity binding site on the target analyte is added to the sample so as to form labeled binding material/analyte/body complexes in the sample. Upon centrifugation, the complexes will settle out in different areas in the tube according to the respective density of the body or bodies; and the degree of label emission of the complex layers can enable qualitative and/or quantitative analyses of the sample to be made. Unbound labeled binding materials will be separated from the complexed layers by the washing action of ascending or descending components of the sample during the centrifugation step. Unbound labeled binding material will thus not interfere with the analysis.

摘要： Target nucleated cells, and target cells containing remnant ribosomal material, which are present in a quiescent anticoagulated whole blood sample are optically detected, enumerated, and analyzed in a sample chamber that has a varying through plane thickness due to convergent opposing sample chamber walls. At least one of the convergent walls of the chamber is transparent so that the blood sample can be observed. The chamber's varying thickness produces a first lesser thickness region in the chamber wherein individual red cells and quiescent monolayers of red cells in the sample will reside after the sample is introduced into and fills the chamber. Larger formed constituents such as white blood cells and nucleated red blood cells present in the sample will reside in greater thickness regions of the chamber, and non-nucleated red cells which reside in such greater thickness regions will agglomerate to form rouleaux. By admixing fluorescent dyes with the blood sample, target cells in the sample can be enumerated and differentiated by means of a scanning instrument which is able to measure different wave length color signals emitted from the target cells in the sample, and differentiate the target cells one from another by reason of the nature of the emitted color signals.

摘要： In order to produce a more well defined interface between adjacent cell layers in a centrifuged sample of anticoagulated whole blood, a material which will bond one group of cells together is added to the blood sample prior to centrifugation. The bonding material must produce a high strength bond between one group of cells, but not effect the other cell types. The material is added prior to centrifugation of the blood sample.

摘要： A biological fluid analysis cartridge is provided. In certain embodiments, the cartridge includes a base plate extending between a sample handling portion and an analysis chamber portion. A handling upper panel is attached to the base plate within the sample handling portion. A collection port is at least partially formed with the handling upper panel. An initial channel and a secondary channel are formed between the handling upper panel and the base plate. The collection port and initial and secondary channels are in fluid communication with one another. A chamber upper panel is attached to the base plate within the analysis chamber portion. At least one analysis chamber is formed between the chamber upper panel and the base plate. The secondary channel and the analysis chamber are in fluid communication with one another.
