摘要： A biologic sample such as feces, sputum, cervical tissue, pleural fluids, exudates, cytologic specimens, or the like, is tested for the presence or absence of: ova; parasites; microorganisms; inflammatory, neoplastic tissue cells; or other target materials which are indicative of infestation, disease or infection. The sample is mixed with a buffer fluid and placed in a transparent tube which contains a volume-constricting cylindrical insert for gravimetric separation of components of the sample. The mixture is centrifuged, and the annular space between the insert and tube bore is examined under magnification for the presence of the target materials.

摘要： The specification discloses a method for enhancing the reliability of screening tests used for detecting the presence or absence of chemical markers associated with gastrointestinal cancer. The method comprises the steps of providing a laxative purge for administration to a patient, collecting a watery fecal sample and then applying the watery fecal sample to a test medium having an indicator to indicate the presence of chemical markers associated with gastrointestinal cancer, if there. Two alternative methods are suggested for obtaining a watery fecal sample. In a first embodiment, the purge is administered to the patient following a recent bowel movement and the first watery post-purge bowel movement is collected. In a second embodiment, the purge is administered to the patient, the first post-purge bowel movement is discarded and the second watery post-purge bowel movement is collected.
摘要翻译：该说明书公开了一种用于增强用于检测与胃肠癌相关的化学标记物的存在或不存在的筛选试验的可靠性的方法。该方法包括以下步骤：向患者提供泻药吹扫，收集水样粪便样品，然后将含水粪便样品施用于具有指示剂的测试培养基，以指示与胃肠癌相关的化学标记的存在（如果有的话）。建议采用两种替代方法来获得水样粪便样品。在第一实施例中，在最近的肠运动之后向患者施用吹扫，并且收集第一次含水的后清除肠运动。在第二实施例中，向患者施用吹扫，弃去第一次清除后肠道运动，并收集第二次含水的清洗后肠道运动。
