The invention relates to a test paper tape which can be used in the gynecological multiprogramming dry-chemistry joint detection. The test paper tape provided by the utility model comprises a dry-chemistry multiprogramming detection test paper tape which consists of a plastic substrate tape and various solidified regent blocks, and sample diluent. The dry regent blocks include combinations formed by increasing or decreasing at least three or more regent blocks of a Ph test regent block, a lactic acid regent block, a hydrogen peroxide concentration regent block, a leukocyte esterase concentration regent block, a neuraminidase activity regent block, an amine test regent block, a proline aminopeptidase substrate reagent block, an oxidase substrate reagent block, a N-acetylamine hexosidase substrate reagent block, a trichomonas specific protease substrate hydrolysis reagent block. the gynecological multiprogramming dry-chemistry joint detection test paper test provided by the utility model can detect Ph, lactic acid, hydrogen peroxide, leukocyte esterase, neuraminidase, amine test, proline aminopeptidase, oxidase, N-acetylamine hexosidase and trichomonas specific protease which are contained in leucorrhea sample at the same time, and can accurately reflect the microorganism environment of a women reproductive tract, the cleanness of leucorrhea secretion and the conditions of Candida albicans, trichomonas, gonococcus and the pathogens of bacterial vaginosis, thereby making the gynecological trichomonas detection more comprehensive; besides, the test paper tape provided by the utility model can be used easily and conveniently, and results can be obtained quickly. If the test paper tape is used together with a gynecological dry-chemistry analyzer, the operation can become easier and the result can be obtained more quickly.

A diagnostic test kit for detecting the presence or absence of an enzyme (e.g., leukocyte esterase) within a test sample is provided. The test kit comprises a substrate that is capable of being cleaved in the presence of the enzyme to release a nucleophilic aromatic compound. The kit also comprises a lateral flow device that comprises a chromatographic medium. The chromatographic medium defines a detection zone within which is contained a first reagent (e.g., diazonium ion) that is capable of reacting with the nucleophilic aromatic compound to form a second reagent (e.g., aromatic azo compound). The second reagent exhibits a color that is different than the color of the first reagent. The lateral flow device also includes an absorbent material located adjacent to the chromatographic medium, the absorbent material receiving the test sample after flowing through the chromatographic medium.

The invention relates to a luteinizing hormone and bacterial vaginosis joint-test kit, in particular to the luteinizing hormone (LH) and bacterial vaginosis (BV) joint-test kit, and belongs to the technical field of test. The kit comprises an LH immunochromatography test paper tape and one or more of a pH test strip, a sialidase test strip, a leukocyte esterase test strip, a hydrogen peroxide test strip and an amine test strip. Preferably, a combination pad and a chromatography film of the immunochromatography test paper tape are respectively wrapped by a corresponding immune labeled antibody and a test antibody. The LH immunochromatography test paper tape and one or more of the pH test strip, the sialidase test strip, the leukocyte esterase test strip, the hydrogen peroxide test strip and the amine test strip are arranged in parallel or arranged on the upper surface and the lower surface of a bottom plate. According to the luteinizing hormone and bacterial vaginosis joint-test kit, by means of self sampling, LH and bacterial vaginosis can be tested simultaneously, the joint-test result can provide a strong evidence for sound child rearing and reasonable contraception, and the luteinizing hormone and bacterial vaginosis joint-test kit is simple and convenient to achieve and suitable for being popularized and used in a large scale.

The present invention relates to the field of infectious diseases. The invention specifically relates to the diagnostic test for acute bacterial pharyngitis. The test is used in screening for Group A Beta Haemolytic Streptococcus by the identifying the presence of leukocyte esterase in the throat. The Leukocyte Esterase Throat Swab Test is compared to the Rapid Step Test for efficiency in terms of fast delivery of results.

The invention discloses leukocyte esterase detection test paper, a preparation method and a detection method. The leukocyte esterase detection test paper comprises a substrate, a buffer solution, a stabilizer, a reaction accelerator, a color developing agent, organic acid, an organic solvent, a surfactant and filter paper. The preparation method comprises: respectively preparing two mixed solutions from the obtained substrate and the color developing agent based on preparation requirements, and mixing the two mixed solutions according to a set mixing ratio to obtain a leukocyte esterase solution; and draining filter paper immersed in the leukocyte esterase solution, rotationally and uniformly flowing, drying the filter paper flatly laid on a drying support plate by using an electrothermal blowing drying box, cutting, and hermetically storing to obtain the leukocyte esterase test paper. The obtained leukocyte esterase detection test paper is respectively used for urine leukocyte esterase detection and vaginal secretion leukocyte esterase detection, so that the operation is simple, and the application is wide.
