Gonorrhea usually requires laboratory tests such as secretion smear, gonococcal culture or nucleic acid amplification test (NAAT).
1. Smear examination of secretion: Usually the doctor will take secretion from the affected area, make a smear, stain it and then put it under the microscope for observation. If gram-negative diplococci are found, it will help in the diagnosis of gonorrhea.
2. Pathogen culture: It is an important basis for the diagnosis of gonorrhea. If gonococcus is found in the culture, the diagnosis is usually clear.
3. Nucleic acid test: It is a molecular biological method such as PCR (Polymerase Chain Reaction) and LCR (Ligase Chain Reaction). It has high sensitivity in diagnosing gonorrhea.
Gonorrhea is caused by gonococcal infection, the incubation period is short, clinical symptoms are more obvious, most of the patients have a clear medical history, generally through the pathogen examination can be clearly diagnosed.
