When hydrogen peroxide concentration is abnormal, it indicates that there is bacterial growth in the vagina, which can lead to dysbiosis and can easily lead to vaginitis, such as trichomoniasis, bacterial vaginitis and mycotic vaginitis. When a woman has an abnormal concentration of hydrogen peroxide in a routine white blood test, she should also pay attention to the presence of mycobacteria or clue cells. When vaginitis occurs, it can also lead to increased leukorrhea, odor, low immunity, etc. In severe cases, it can lead to cervical inflammation or endometritis, which can be detrimental to a woman’s health.
