A positive hydrogen peroxide with a plus sign is usually a test for vaginal secretions. A positive hydrogen peroxide with a plus sign indicates a change in the vaginal microenvironment, possible dysbiosis or inflammatory infection, which is usually not serious. In general, normal vaginal discharge is negative for hydrogen peroxide. If the test is only positive for hydrogen peroxide with one plus sign and no other abnormal results and no perineal discomfort, the test is usually mild and may be due to a slight dysbiosis caused by a decrease in the main bacteria in the vagina, Lactobacillus, causing a temporary positive or false positive hydrogen peroxide. You can slowly restore the balance of the micro-ecosystem in the vagina by good personal hygiene, changing underwear regularly, cleaning the vulva and exercising. If there are other abnormal results, such as itching and pain in the vaginal area, odor, yellowing and increase in the discharge, or discomfort during intercourse, the infection may be caused by bacteria, viruses, parasites and other microorganisms, resulting in inflammation. You can take the secretion to do the culture of the secretion or drug sensitivity test, according to the results of anti-bacterial, fungal, viral or parasitic treatment. Generally hydrogen peroxide positive a plus can be recovered after personal adjustment or systemic treatment, most of which will not leave sequelae, but if the inflammation is prolonged, it may also induce diseases such as polyps in the genital tract, so timely treatment is recommended.
