A weak positive sialoglucosidase test indicates the possible presence of bacterial vaginitis because sialoglucosidase is produced by some anaerobic bacteria in the vaginal flora as well as Gardnerella, and its levels are normally low and do not cause inflammation. However, if the normal micro-ecological balance in the vagina is disrupted, these pathogenic bacteria can overgrow and cause bacterial vaginitis. Therefore, clinical diagnosis is supported by the measurement of sialoglucosidase, which is usually diagnosed when its value is greater than or equal to 7. It is recommended that when abnormal leucorrhea, vulvar itching or odor is evident, one should go to the hospital for internal gynecological examination and routine leucorrhea examination as soon as possible and use anti-inflammatory drugs under the guidance of the doctor. In addition to the treatment, you should also pay attention to personal hygiene, wash and change your underwear regularly, avoid unclean sex, wash your pubic area with warm water, and do not eat spicy and stimulating food.
