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.

摘要翻译： 可以通过将透明管中的血液样品离心来诊断患者的健康，该管包含一个或多个不同密度的浮体，插入物，脂质体或塑料珠的主体或组。 每个密度定义的身体携带分析物 - 捕获结合材料，例如抗原或抗体，其对靶分析物是特异性的，或靶分析物上的其它特异性高亲和力结合位点，其目标分析物可能在待测试的血液或其他样品中; 并且其分析物的水平表示患者的健康。 将至少一种对靶分析物上的表位或其他特异性高亲和力结合位点特异性的标记结合物质加入到样品中，以便在样品中形成标记的结合材料/分析物/身体复合物。 离心后，复合物将根据身体或身体的相应密度沉淀在管中的不同区域; 并且复合层的标签发射程度可以使得要进行样品的定性和/或定量分析。 通过在离心步骤期间样品的上升或下降组分的洗涤作用，未结合的标记结合材料将从复合层分离。 因此，未结合的标签结合材料不会影响分析。
