    • A method for analyzing blood enables one to isolate, detect, enumerate and confirm under magnification the presence or absence of target cancer cells and/or hematologic progenitor cells which are known to circulate in blood. The analysis is performed in a sample of centrifuged anticoagulated whole blood. The analysis involves both morphometric and epitopic examination of the blood sample while the blood sample is disposed in a centrifuged blood sampling tube. The epitopic analysis of the presence or absence of cancer cells relies on the detection of epitopes which are known to present only on cancer cells; and the epitopic analysis of the presence or absence of hematologic progenitor cells relies on the detection of epitopes which are known to present only on hematologic progenitor cells. The targeted epitopes on the target cell types are epitopes which are also known to be absent on normal circulating blood cells; and the target cancer cell epitopes are epitopes which are known to be absent on target hematologic progenitor cells. Fluorophors with distinct emissions are coupled with antibodies which are directed against the targeted epitopes. The morphometric analysis is performed by staining the cells in the blood sample with an intracellular stain such as acridine orange which highlights the intracellular cell structure. Both the morphometric and epitopic analyses are preferably performed at or near the platelet layer of the expanded buffy coat in the centrifuged blood sample. The morphometric analysis and/or the epitopic analysis may be performed under magnification both visually and/or photometrically.
    • 用于分析血液的方法使得能够在放大下分离,检测,枚举和确认已知在血液中循环的靶癌细胞和/或血液祖细胞的存在或不存在。 在离心的抗凝全血样品中进行分析。 该分析涉及血液样品的形态测定和表征检查,同时将血液样品置于离心取样管中。 癌细胞存在或不存在的代表性分析依赖于已知仅存在癌细胞的表位的检测; 并且血液祖细胞存在或不存在的表征分析依赖于已知仅存在血液祖细胞的表位的检测。 目标细胞类型上的靶向表位是已知在正常循环血细胞上不存在的表位; 并且目标癌细胞表位是已知在靶血液祖细胞上不存在的表位。 具有明显排放的荧光素与针对靶向表位的抗体相结合。 通过用细胞内染色剂如吖啶橙染色血液样品中的细胞进行形态测定分析,突出细胞内细胞结构。 形态测定和表征分析优选在离心血液样品中在扩张的血沉棕黄层的血小板层或其附近进行。 形态测定分析和/或表征分析可以在视觉上和/或光度下放大进行。
