The invention discloses a test paper for rapidly detecting swine fever antibody and a preparation method thereof. The inventive test paper consists of a sample pad (4), a glass fiber member (3), a cellulose nitrate membrane (2), a water absorbent pad (1) and a support (5); wherein the cellulose nitrate membrane contains a detection line (6) coated by swine fever virus E2 protein and a reference line (7) coated with rabbit anti swine fever antibody; and the glass fiber member is combined with swine fever virus E2 protein marked by colloidal gold. The test paper can rapidly detect possibly present swine fever antibody in a sample to achieve rapid detection and timely epidemic control, thus creating favorable conditions for further separation and identification. The test paper has the advantages of convenient, rapid and easy usage, clear result, easy generalization, and no need for special instrument and equipment as well as professionals, and is suitable for large-batch onsite detection for base layer and for sudden events. The test paper is suitable for epidemic inquisition and performs assistant effect on swine fever virus infection diagnosis.

The invention provides a colloidal gold test strip for the detection of measles and rubella virus specific IgM antibodies. The measles specific gene engineering antigen H, the rubella virus specific gene engineering antigen E1, and a quality control double-antibody IgG are simultaneously coated on a nitrate cellulose film (NC film), and a membrane chromatography double antigen sandwich method is adopted to detect the measles and rubella virus specific IgM antibodies in a specimen in combination with a colloidal gold labeled anti-human IgM. The test strip is simple in operation, convenient, and fast, and has the advantages of no requirements of special instruments and special training, clear and identified result, and easy popularization. The test strip is suitable for base and site detection and epidemiological investigation, has auxiliary and differential diagnosis effects on measles and rubella virus infection, and can be used for the immune effect observation after vaccination.

The invention discloses a detection test paper. The test paper comprises (1) a reaction support, (2) a water absorption pad, (3) a nitrocellulose membrane, (4) a gold-labeled antibody adsorption membrane and (5) a sample pad, wherein the nitrocellulose membrane is coated with a detection strip and a quality control strip of a staphylococcal enterotoxin B antibody and a quality control antibody; and the gold-labeled antibody adsorption membrane contains the staphylococcal enterotoxin B antibody labeled by colloidal gold. The test paper can be matched with a small instrument to carry out semi-quantitative detection, does not need professional training, has clear and identifiable result, can objectively store data, is simple to operate, easy to popularize, suitable for a basic level, suitable for field detection of emergency and suitable for epidemiological investigation, and plays an auxiliary role in diagnosis of staphylococcal enterotoxin B infection.

This invention provides one test bar, which comprises the following steps: a, covering A set of group wheel virus single clone antibody and IgG two ban NC fiber film; b, comprising glue gold label A set wheel single clone antibody glass fiber film; c, applying film analysis double antibody clamper to test A set wheel virus of feces.

This invention provides one test bar, which comprises the following steps: a, covering syncytium virus antibody of respiratory tract and IgG two band NC fiber film; b, comprising glue gold label respiratory syncytium virus single clone antibody glass fiber film; b, applying film analysis double antibody clamper principle to test nose secretion respiratory virus.

The invention provides a test strip for rapid detection of a leptospira antibody, which comprises a reaction film and a conjugate release pad. The reaction film has a detection band simultaneously coated with Leptospira specific antigen ompL1 and LipL32, and a quality control band of polyclonal antibody coated with rabbit anti-Lebtospira specific antigen. The conjugate release pad is coated with colloidal gold labeled Leptospira specific antigens ompL1 and LipL32, and a membrane chromatography double antigen sandwich method is adopted to detect the Leptospira specific antigens ompL1 and LipL32 in a specimen. The test strip is simple in operation, convenient, and fast, and has the advantages of no requirements of special instruments and special training, clear and identified result, and easy popularization. The test strip is suitable for base and site detection and epidemiological investigation, and has auxiliary effect on the diagnosis of leptospiral infection.

The invention relates to the technical field of immunoassay, and especially relates to a fluorescence immunoassay method of procalcitonin in saliva. A saliva collector, saliva, an anti-procalcitonin antibody, a fluorescence reagent and a detector are used in the invention. The saliva collector comprises one or a combination of a collecting tube, a collecting rod and a collecting scraper sheet; the anti-procalcitonin antibody is one or a combination of an anti-procalcitonin monoclonal antibody and an anti-procalcitonin polyclonal antibody; the fluorescence reagent is a liquid phase and/or solid phase material containing a fluorescent substance, and the fluorescent substance is one or a combination of organic fluorescence dyes or rare earth element fluorescence dyes; and the detector is a fluorescence detector. The method adopting human body saliva as a detection sample has the advantages of effective monitoring of procalcitonin in saliva, strong specificity, good repeatability, high sensitivity, simplicity in operation, no special devices, no professional training, clear and distinguishable result, easiness in promotion, and suitableness for onsite detection.
