The leucorrhoea test begins by emptying the urine and taking a bladder truncated position on the examination bed, that is, with the body lying flat and the legs apart. The doctor takes out a vaginal speculum with sterile gloves and gently places it into the patient’s vagina. Dab the secretion on the speculum onto the slide prepared in advance with saline, and then send the slide for examination to check whether the secretion is inflammatory or not. This method is better to see the color and nature of the secretion, and also to see whether there is inflammation in the cervix, which is good for clinical judgment. The process of taking the leukorrhea is easy, safe and painless by using a long cotton swab to dip the discharge deep into the posterior fornix of the patient’s vagina and then put it into saline for sending it for examination.
