Leukocyte esterase positive hydrogen peroxide positive is the result of a routine leukocyte test which indicates that the microecology of the vagina has lost its balance and other microorganisms in the vagina are proliferating, mainly Gardnerella and other anaerobic bacteria are overgrowing to the detriment of the normal lactobacilli in the vagina, suggesting bacterial vaginitis. Leukocyte esterase is only present in neutrophils and not in other cells. A positive leukocyte esterase indicates an increase in neutrophils and is considered inflammatory. Positive hydrogen peroxide also indicates inflammation. You can douche the vagina with cleanser, insert metronidazole vaginal gel, and take oral metronidazole tablets for one week.
