Abstract

The invention discloses a coagulase detection reagent, a reaction pad, a preparation method thereof and a kit. The coagulase detection reagent comprises reaction agents and a color developing agent, the reaction agents include morpholine ethane sulfonic acid, cane sugar, polyvinylpyrrolidone and glycyl-protamine tetramethoxy-beta-naphthylamine, the reaction pad comprises a carrier and ingredients of the reaction agents, and the ingredients of the reaction agents are coated on the carrier. The preparation method of the reaction pad includes: 1), dissolving the cane sugar, polyvinylpyrrolidone and glycyl-protamine tetramethoxy-beta-naphthylamine in morpholine ethane sulfonic acid to obtain soaking liquid; 2), putting the carrier in the soaking liquid, taking out after sufficient soaking, and drying to obtain the reaction pad. The reaction pad obtained by the preparation method is combined with ingredients of the detection agent to be applied in preparing the kit which is high in sensitivity and accuracy.

Description

technical field [0001] The invention relates to the field of detection reagents for aerobic bacterial vaginitis, in particular to a coagulation enzyme detection reagent, a reaction pad, a preparation method thereof and a kit. Background technique [0002] Vaginitis is an inflammation of the vaginal mucosa and submucosal connective tissue, and is a common disease in gynecological clinics. For normal healthy women, due to anatomical and biochemical characteristics, the vagina has a natural defense function against the invasion of pathogens. When the natural defense function of the vagina is destroyed, pathogens are easy to invade and cause vaginal inflammation. There are three types of common vaginitis: bacterial vaginosis (BV / AV), fungal vaginitis (VVC) and trichomonas vaginitis (TV). Among them, female bacterial vaginal infection can be divided into two types, one is caused by anaerobic bacteria and facultative anaerobic bacteria, clinically called bacterial vaginosis (BV),...
