Bacterial vaginosis test kit BV001

chromogenic

For qualitatively testing activity of neuraminidase in female’s vaginal fluid, only for auxiliary diagnosis of bacterial vaginosis. [Testing principle] Neuraminidase is one of pathogenic factors of bacterial vaginosis (BV). Activity of neuraminidase in vaginal fluid of BV women is significantly higher than that in vaginal fluid of normal women; there is no or only a small amount of neuraminidase in vaginal fluid of normal women. By testing for neuraminidase higher than normal level in the vaginal fluid, patients can be diagnosed whether have BV. This kit mainly contains bacterial neuraminidase-specific chromogenic substrate solution. When the reagent contacts neuraminidase in the sample, the substrate is hydrolyzed to produce sialic acid and chromophoric groups, chromophoric groups are further changed to blue by oxygen in air, and test results are read immediately after specified reaction time. Bacterial vaginosis is positive if the solution or swab head becomes blue, and bacterial vaginosis is negative if the solution or swab head does not change color. [Storage conditions and validity] Have a validity of 12 months when stored in 2℃ - 8 ℃ in non-corrosive gas in dry placesprotected from light. [Applicable instruments] Water-proof incubators or water-bath heaters that can be controlled to 35-37 ℃ [Sample requirements] 1. Rotate for 10-20 s at posterior fornix of vagina to collect as much vaginal fluid of the patient as possible until fluid can be clearly seen on the swabs. 2. Samples shall be collected during non-menstrual period, sexual intercourse, tub bath, vaginal douche and local drug use shall not be allowed during 24 hours before sample collection,
