Gonorrhea is a bacterium that is found in the male urethra and female cervix. It is a purulent infection of the genitourinary system caused by gonococcal infection and is mainly transmitted through sexual contact. Usually, patients will experience symptoms such as frequent and painful urination and purulent discharge. To confirm the diagnosis of gonorrhea, antigen test, genetic test, smear test, culture test and other tests can be done. Antigen testing is performed by the EIA test for gonococcal antigens. The smear test is mainly for patients with a large amount of purulent secretion, and a positive test result of about 90% will confirm the diagnosis of gonorrhea. If the smear does not confirm the diagnosis, a gonococcal culture can be performed. Because of the special physiological structure of women, their vagina hosts a large number of other bacteria, and the smear test results are easily affected, so for female gonorrhea patients, the gonococcal culture test is mostly used. Genetic testing mainly involves taking epithelial cells from patients for nucleic acid amplification and is mainly used for patients who do not have obvious clinical symptoms. In addition, gonorrhea can also be screened for effective treatment by gonococcal drug sensitivity testing. Gonorrhea is a common sexually transmitted disease, so it is important to be clean and avoid having too many sexual partners, and once a couple is infected with an STD, they should be treated promptly and resume normal life after being cured.
