During a routine white blood test, it is normal to have a white blood cell count between 0 and 15. If the number of leukocytes exceeds 15, a bacterial infection in the vagina is considered and topical treatment with metronidazole suppositories is recommended. The range of leukocytes during the routine leukocyte examination is only able to determine the presence of bacterial infection in the vagina. If the leukocyte examination is positive for mycobacteria or Trichomonas vaginalis and the pH of the leukocyte is not between 4 and 4.5, the leukocyte is abnormal. After the routine leucorrhoea test, it is recommended to get the results of the test to a professional doctor for analysis. If there are abnormalities in the leukorrhea, prompt interventional treatment should be given as prescribed by the doctor to avoid further development of the inflammation and aggravation of the original discomfort of the vagina. The most common symptoms of vaginitis are increased leucorrhea, odor and vulvar itching, and routine leucorrhea examination is recommended when these symptoms occur.
