Leukocyte esterase is a specific indicator that reacts to the presence of leukocytes in the specimen being tested, and leukocyte esterase reacts only to neutrophils. A positive leukocyte esterase test indicates the presence of neutrophils in the leukocytes, suggesting a gynecological infection such as vaginitis, cervicitis, endometritis, etc. The results of leukocyte esterase alone do not accurately reflect the location of the inflammatory lesion and the specific type of pathogenic microorganism, but need to be combined with routine leukocyte examination, pathogenic microorganism examination, and routine gynecological examination to make a clear diagnosis. If the diagnosis of bacterial vaginosis is confirmed, you may consider placing tinidazole vaginal tablets in the vagina for treatment.
