Leukocyte esterase and hydrogen peroxide tests are routine tests for vaginal secretions, and a positive test indicates vaginal inflammation. 1. Positive leukocyte esterase: Leukocyte esterase is found in neutrophils. Positive leukocyte esterase suggests elevated neutrophils and inflammation. 2. Positive hydrogen peroxide: Positive hydrogen peroxide often suggests the presence of vaginal flora dysbiosis or bacterial vaginitis. Sexual behavior, sex hormone changes, antibiotic abuse, and improper vaginal douching can cause vaginal abnormalities and lead to hydrogen peroxide positivity. Positive leukocyte esterase and hydrogen peroxide tests are recommended to go to a regular hospital and follow the doctor’s instructions for active treatment.
