Gonorrhoea Testing: How Doctors Diagnose the Infection

31 Oct 2025

Whether you have symptoms of gonorrhoea, or are just being cautious about your health, knowing what to expect from the testing process can put your mind at ease and ensures you are making the right decisions when it comes to protecting your as well as your partner’s health. So what can you expect from gonorrhoea testing?

Gonorrhoea infection is typically tested for through one or more of the following methods, based on the site of infection:

• Genital swab collected from the urethra or cervix, or tip of the penis
• Throat swab
• Rectal swab
• Urine sample

Keep reading to learn about the types of tests which help detect gonorrhoea, how long you need to wait before testing for gonorrhoea, and how soon you can receive your test results.

How do they test for gonorrhoea?

Gonorrhoea is tested for through a fluid sample, which could be collected through one of the four following methods. You may have to go through several of the methods based on the site of infection.

Genital Swab

The most frequent approach that a sexual health testing provider will test you for gonorrhoea is by collecting a simple swab of your genital area with a sterile cotton bud (typically smaller than a regular cotton bud). The procedure takes just a few seconds to do and usually is not painful. A genital swab may include a swab from your urethra or cervical region, if you have a vagina or swabbing from the tip of your penis or urethra.

To ensure the maximum accuracy of your genital assessment, avoid using gels, creams or douches in and around the vagina for 24 hours before your appointment.

Rectal Assessment

If you suspect to have come in contact with gonorrhoea from penetrative anal sex, a rectal assessment is the best approach to swab the area to test for gonorrhoea. Similar to the genital assessment, the medical provider will use a sterile cotton bud to go about 2 to 3 cm inside the rectal area and will be taking a sample.

To ensure that you receive 100% accurate test results, a rectal assessment should be performed in conjunction with a throat and genital assessment to ensure you have not contracted the infection in the remaining areas.

Throat Swab Test

A throat swab testing for gonorrhoea is similar to a rectal swab or genital swab test, and is only done if there is a concern for an oral gonorrhoea infection (if you had unprotected oral sex with a person with gonorrhoea in their genital area). This is done by collecting a swab sample from the back of your throat for testing, and the swabbing process might be slightly uncomfortable, but this discomfort subsides within a few seconds.

Urine Sample

Collecting a urine sample is the ideal non-invasive process and is sometimes used, but not nearly as common, for testing gonorrhoea in the genital area. You need to use a sterile cup to collect the first part of your urine stream, after which the cup will be sealed and sent to the laboratory for testing. Make sure to not urinate for up to 1 to 2 hours prior to your appointment for accuracy at the time of testing.

Women are not generally asked to give a urine sample for gonorrhoea because it is inaccurate compared to a vaginal swab sample, so urine is usually recommended for men only. Therefore, if you were to get a gonorrhoea infection from your partner during anal or oral sex, you would want to complete a swab sample rather than a urine sample.

Where Can You Get a Test for Gonorrhoea?

Gonorrhoea is one of the most common STIs in the UK, and is readily available as a test. You can access these testing services from:

• Your local GP
• A GUM (genitourinary medicine) Clinic
• A Private Sexual Health Clinic
• Online, through a postal testing service

At South Kensington MD, our private sexual health clinic is ready to help patients throughout the UK. And by going private, you have the advantage of avoiding long waits unlike the NHS, and it is more discreet, as it is not filed on your NHS medical history.

How Long Should You Wait Before Testing for Gonorrhoea?

It is advised to wait a minimum of 14 days (2 weeks) after suspected exposure to gonorrhoea prior to testing. Testing too early may provide a false negative, due to the presence of Neisseria gonorrhoeae or gonococcus bacteria being undetectable, therefore providing a “false negative” result.
