The white blood test has bacilli, which the laboratory often refers to as Lactobacillus. If there are more lactobacilli in the vagina, it means that the vaginal flora is normal and the local resistance is stronger, so it is not easy to attract pathogenic bacteria. If Lactobacillus is decreased, it means that the internal environment of the vagina has become dysbiosis and may lead to pathogenic infection, which may cause clinical symptoms such as increased vaginal discharge, yellowish color or itching of the vulva. If these symptoms are present, clinical treatment with medication is recommended. If lactobacillus is found to be reduced or almost absent in the leucorrhoea test, vaginal insertion of lactobacillus capsules is recommended for treatment, mainly to improve the local resistance.
