    • A method for detection of mycobacterium tuberculosis antigens in biological fluids provides immunoassay methods, diagnostic kits, and an immunochromatoraphic assay device for detection of Mycobacterium tuberculosis antigens in biological specimens, preferably body fluids and tissues. The preferred body fluids are blood, serum, plasma, urine, pulmonary fluid, sputum, cerebrospinal fluid, and the preferred tissue is the lung biopsy specimen. The immunoassays require two primary antibodies against RD1, RD2, or RD3 of Mycobacterium tuberculosis. At least one of the primary antibodies is attached to a solid carrier. Optional, a second antibody against an animal species producing one of the primary antibodies can be added. Either the other primary antibody or the secondary antibody is labeled with a detection agent, which can be an enzymatic marker, a fluorescent or luminescent agent, a radio active label or a color particle. The biological specimens may be used directly, concentrated or diluted for the immunoassays.
    • 用于在生物流体中检测结核分枝杆菌抗原的方法提供免疫测定方法,诊断试剂盒和用于在生物样品中优选体液和组织中检测结核分枝杆菌抗原的免疫色谱测定装置。 优选的体液是血液,血清,血浆,尿液,肺液,痰液,脑脊液,优选的组织是肺活检标本。 免疫测定需要针对结核分枝杆菌的RD1,RD2或RD3的两种一抗。 至少一种第一抗体连接到固体载体上。 可以加入针对产生其中一种抗体的动物物种的第二抗体。 另一个一抗或二次抗体用检测剂标记,其可以是酶标记物,荧光或发光剂,无线电活性标记物或着色颗粒。 生物标本可直接使用,浓缩或稀释用于免疫测定。
