    • The invention relates to a method for quantitating the level of a preselected analyte in a sample of blood of a human or animal patient by incubating the test sample with an antibody specific to the analyte to form an immunocomplex, which then interacts with the white blood cell fractions and result in the production of oxidants. Oxidants are detected using chemiluminescent reagents. In addition, the white blood cell oxidant response may be enhanced by the inclusion of certain agents such as opsonized zymosan. As part of the assay, separate blood samples are also maximally stimulated with a maximal stimulatory amount of exogenously-added antigen, and corresponding antibody, to form immunocomplexes, to provide a response factor used in the quantitation of analyte. This quantitative method may be used to determine levels of analytes in a sample of a patient's blood including endotoxin and other analytes related to sepsis, in order to select the proper therapeutic course, or may be used to measure other analytes such as inflammatory mediators, hormones, acute phase proteins, toxins, drugs of abuse, markers of cardiac muscle damage, therapeutic drugs, cytokines, and chemokines.
    • 本发明涉及通过将测试样品与特异于分析物的抗体孵育以形成免疫复合物(其然后与白细胞相互作用)来定量人或动物患者血液样品中预选分析物的水平的方法 导致氧化剂的生成。 使用化学发光试剂检测氧化剂。 此外,白细胞氧化剂反应可以通过包括某些试剂例如调理的酵母聚糖来增强。 作为测定的一部分,分离的血液样品也用最大刺激量的外源加入的抗原和相应的抗体最大程度地刺激以形成免疫复合物,以提供用于定量分析物的响应因子。 该定量方法可用于确定患者血液样品中包含内毒素和与败血症有关的其他分析物的样品中的分析物水平,以选择适当的治疗过程,或可用于测量其他分析物,如炎症介质,激素 ,急性期蛋白,毒素,滥用药物,心肌损伤标志物,治疗药物,细胞因子和趋化因子。

Oxidants are detected using chemiluminescent reagents. The assay is performed on the sample and in addition includes a measurement of the oxidant production resulting from a maximal stimulatory dose of immunocomplexes, providing a ratio to indicate the level of analyte in the sample. The white blood cell oxidant response may be enhanced by the inclusion of certain agents such as zymosan. This method may be used to determine levels of analytes in a sample of a patient's blood including endotoxin and other analytes related to sepsis, in order to select the proper therapeutic course, or may be used to measure other analytes such as inflammatory mediators, hormones, acute phase proteins, toxins, drugs of abuse, markers of cardiac muscle damage, therapeutic drugs, cytokines, and chemokines. Additional parameters derived from the assay include maximal chemiluminscent response and responsiveness to aid in the staging of sepsis.
