LBG grading refers to the vaginal microecological grading, which is described below. LBG1 refers to a vaginal microflora that is dominated by Lactobacillus polymorphus, with no or very few other bacteria. LBG2a refers to a vaginal microflora that is mixed, but dominated by Lactobacillus. LBG2b means that the vaginal microflora is a mixed flora, but the proportion of Lactobacillus is significantly reduced and less than the other flora. LBG3 grade refers to a severe reduction or absence of Lactobacillus and an overgrowth of other bacteria. The lLBG classification is primarily used to determine the health of the vaginal microbial system, with grades 1 and 2a being relatively healthy, 2b being the next healthiest, and 3 being the worst. If you want to diagnose vaginal inflammation, you also need to combine with other tests, such as white blood cell count, the number of white blood cells containing toxic particles, background colonization, etc., to improve the various tests, and active treatment should not be negligence, so as not to avoid misunderstanding the condition.
