Vaginal microecological examination can mainly detect the content of probiotics and harmful bacteria in the vaginal environment, and the main index is vaginal pH value. Vaginal microecological examination makes the treatment of infectious diseases of the reproductive tract, from the original discovery of pathogenic bacteria, kill pathogenic bacteria, to pay attention to microecological diagnosis and treatment to put forward the concept of personalized treatment plan change. Its detection method can be divided into two aspects: 1. Morphological examination: mainly check epithelial cells, trichomonas, mycelium, spores, mycoplasma-like vesicles, chlamydia-like vesicles and so on. 2. Examination of dry chemical analysis: the main indicator is vaginal PH value, vaginal PH value is the most direct indicator of vaginal ecological balance; hydrogen peroxide concentration check, is an indicator of ecological dominant bacteria; leukocyte esterase check is to reflect the host’s indicators; salivary acid glycosidase activity check, is to reflect the indicators of pathogenic bacteria. After the above two aspects of the index examination, according to the software comprehensive evaluation, to achieve the purpose of understanding microecology, recognize pathogens and damage objects, so as to guide the treatment. If you have any other questions, it is recommended to consult a professional doctor for guidance.
