Abstract

The invention relates to biology applied technology field, especially relates to a immune chromatography assay for quickly detecting the human immunologic deficiency disease (HIV) antibody and antigen. The assay comprises two independent test papers A and B and plastic case C for storing the test paper, wherein the test paper A is used for detecting the HIV antibody and the test paper B is used for detecting the HIV p24 antigen. The test paper A and test paper B are parallely encased in the plastic case to constitute the assay. On detecting, the detected sample is added on the sample pad of the test paler and the immunoreaction result is directly observed to perform detection. The assay is used for screening or clinical diagnosis of the HIV infection and at the same time the HIV antigen and antibody are detected, the simpler antibody detection can effectively reduce the window phase for detecting the HIV, with features of quick reaction, easy operation, economy and practicality, suitable for insitu detecting.

Description

technical field [0001] The invention relates to the technical field of biological applications, in particular to an immunochromatographic kit for combined rapid detection of HIV antibodies and antigens. Background technique [0002] Acquired Immunodeficiency Syndrome (AIDS), referred to as AIDS, is a serious infectious disease caused by human immunodeficiency virus (Human immunodeficiency virus, HIV) infection. Since the first AIDS patient was diagnosed in the United States in 1981, according to the latest WHO data, by the end of 2007, there were estimated to be 33 million HIV-infected people in the world, and there were about 700,000 HIV-infected people in China. [0003] HIV transmission routes mainly include blood transmission, sexual contact, drug injection and mother-to-child transmission. The average incubation period in the human body is 7 to 10 years. Patients in the latent period of HIV infection have no obvious clinical symptoms, but are highly contagious. Detec...
