Women who have 20-30 leukocytes/HP in the routine leukorrhea test are mostly suggestive of bacterial infections. If there are only elevated leukocytes in the leukorrhea test and no other abnormalities, anti-inflammatory lotions can be given to clean the vulva and vagina, and then metronidazole suppositories or tinidazole suppositories can be placed inside the vagina to treat the disease. If there are also 20-30 leukocytes/HP and trichomonas is detected, then it is a case of trichomoniasis. If there is mold growth at the same time, it is mycosis vaginalis, which can be treated with appropriate medication according to the growth of different bacteria. Normally, the vaginal environment is weakly acidic, due to the growth of lactobacillus bacteria to maintain the weak acidic balance of the vagina, the presence of leukocytosis can lead to bacterial infections.
