Gonorrhea should be examined in the hospital under the guidance of an STD doctor. The main examination methods include direct smear examination of secretions, gonococcal culture, nucleic acid examination, etc., as follows: 1. Direct smear examination of secretions: take secretions from the urethra, cervical or other diseased parts of the patient, and then observe them under a microscope by smearing and staining. If you have gonorrhea, you will find gram-negative diplococci in the white blood cells. However, this method has limitations and is suitable for untreated male patients with acute urethritis. 2. gonococcal culture: typical colonies can be seen through the culture of the secretion, and this test is suitable for patients with insignificant or mild symptoms. 3. nucleic acid detection: the polymerase chain reaction technique is applied to detect and diagnose gonococcal occult plasmids with high sensitivity by making a specific diagnosis. If the test result is positive, gonorrhea is present. In addition, since gonorrhea is highly contagious, once diagnosed, treatment should be carried out in a timely manner under the guidance of a doctor, and sexual partners should be examined and treated together to avoid cross-infection, so that recurrence will not occur after cure.
