Which of the following tests helps diagnose gonorrhea?

The diagnosis of gonorrhea can be effectively accomplished through a urine test. This type of test detects the presence of Neisseria gonorrhoeae, the bacteria responsible for the infection, by analyzing a sample of the urine for genetic material or proteins associated with the organism. It is a non-invasive method, making it convenient and easy for the patient.

Other testing options exist, such as swabs from potentially infected areas, but in terms of the options provided, the urine test is widely recognized and used for its accuracy and ease of collection.

In contrast, blood tests are not typically utilized for diagnosing gonorrhea, as they are more suited for other infections or determining immune response rather than direct detection of the bacteria. X-rays and endoscopy are procedures not relevant to the diagnosis of gonorrhea, as they serve entirely different purposes in medical imaging or examination of internal structures. Thus, the urine test stands out as the primary reliable means of diagnosing gonorrhea from the choices available.
