Bleeding during a leukorrhea test can be caused by the following reasons: 1) Vaginal inflammation leads to severe congestion and edema of the vaginal mucosa, which can cause the mucosa to break and bleed during the test, as long as the inflammation of the vagina is cured, the bleeding will naturally stop, and the local area should be kept clean during the treatment period. 2) Bleeding can be caused by localized lesions on the cervix, which may lead to local bleeding through contact with the cervical polyps or cancerous lesions, and should be taken seriously. If there is chronic inflammation of the cervix, cervical polyps or cancer, the contact may cause local bleeding phenomenon, which should be highly valued, and cervical cancer screening can be done to exclude whether there are local lesions of the cervix and whether there is the possibility of cancer.
