The methods for detecting gonorrhea generally fall into two main categories. One involves testing for the pathogen of gonorrhea. A simple method is the microscopic examination of Neisseria gonorrhoeae, which can be seen under a microscope as Gram-negative diplococci. Another method is the cultivation of Neisseria gonorrhoeae, although culturing with medication can occasionally result in false negatives. A more advanced and accurate method is PCR (Polymerase Chain Reaction), which involves using a urethral swab to detect the DNA of Neisseria gonorrhoeae. Currently, this is considered the most sensitive and accurate method available.
