Positive hydrogen peroxide is normal, mainly because it is produced by Lactobacillus in the vagina and has the effect of inhibiting or killing other pathogenic types of bacteria. If the test is positive for hydrogen peroxide alone, it is normal and does not require any special treatment. If the test is positive for hydrogen peroxide and is accompanied by an increase in vaginal discharge, yellow discharge with odor and vulvar itching, bacterial vaginitis is the cause. If the diagnosis of bacterial vaginitis is confirmed, the treatment is mainly oral with topical metronidazole, avoiding sexual intercourse and bathing during the treatment period to avoid affecting the therapeutic effect. Since the vagina has a normal flora, excessive cleaning is not necessary to avoid dysbiosis of the vaginal flora.
