Urine Test for Sexually Transmitted Diseases

Testing for sexually transmitted diseases (STDs) in a walk in STD clinic in London with the urine is becoming more available these days. Through the improvements, it is now possible to detect many types of STDs using urine testing. Urine test for chlamydia and gonorrhoea is preferable than the cervical and urethral swabs. It is currently becoming a standard practice.

It is less common to findurine test for other STDs like human papillomavirus (HPV) and trichomoniasis.

Why use urine testing for STDs?

Many people found testing for STDs uncomfortable, especially when testing for a bacterial infection. Men felt this discomfort more when they were tested for chlamydia or gonorrhoea since the swab had to be inserted into their urethra.

For women, it was a pelvic exam. For this exam, a cervical swab will have to be collected and tested for the bacteria. This discomfort made people more discouraged about testing for sexually transmitted infections.

The reduced number of testing made asymptomatic STDs become more like an epidemic. This is because many STDshave no symptoms and could only be detected through screening. When the infected do not know their statuses, they share it with their partners who will, in turn, transmit it to others if they had more than one.

Unlike swab testing, urine testing is more comfortable to undergo. This has encouraged many people to test and receive treatment for STDs regularly. However, urine testing is not a standard component of the majority of the annual exams.

Differences between urine testing and bacterial culture

Urine testing is one of the standard methods for detecting bacterial STDs like gonorrhoea and chlamydia. These are the two most available urine testing for STDs; the one for trichomoniasis is available but not so common.

The standard for diagnosing bacteria STDs like chlamydia and gonorrhoea is through bacterial culture. In this test, the focus is to grow the bacteria out of the samples of the urethra or cervix.

This, being the gold standard does not mean it is the most preferred. Many people choose to undergo bacterial DNA testing. This testing just looks for the bacterial DNA in the sample instead of going to grow the bacteria. The bacteria DNA testing uses the ligase chain reaction (LCR) or any other method for amplifying DNA.

These two testings are very sensitive that they can detect even the smallest amount of bacterialDNA. These tests donot need the bacteria to be alive before they can be discovered. It is possible to miss out on some with the urine testing, but the urethral and cervical swab gives no room for that.

Many people, however, are still sceptical about getting a chlamydia and gonorrhoea test with urine like they are when being required of a physical examination.

What are the risks and contraindications?

The urine test is safe. You will give your urine sample to the doctor. The doctor will then send it to the lab to perform some tests to know whether it contains bacterial DNA. Urine testing for STDs has no contraindication.

What to do before the test

This test does not need special preparation. However, before undergoing the test or any test for STD, it is wise you discuss with your doctor about the type of STD you will be tested for. Ask him why he recommendsthat particular test. Also, ask him whether you need to undergo some tests if you are at risk of any other STD.

Also, you should discuss how long it will take for your result to be ready, and whether you will have to come to the doctor to receive the result if it turns out negative. Some clinics will only contact you if your result is positive.

During and after the test

A regular appointment is what you need for a urine STD testing. You will be given a sample container where the doctor will ask you to urinate inside. The medical staff who is responsible will provide you with this sample container.

What does the result mean?

Within some hours, the result for STD testing for bacterial DNA will be ready. If the test used for you is the XPert CT/NG, you will receive your results within  90minutes.

Having a positive result means that the bacterial DNA has been detected and youare infected. The way out is usually a treatment. If the test result turns out negative, it means that at the time of the test, no evidence of the bacteria could be detected in you.

So, if you have a positive chlamydia test, it means you have chlamydia, and if you have it positive for gonorrhoea, it means you have gonorrhoea. The negative result for chlamydia means you do not have chlamydia. The same applies for gonorrhoea, and any other test you could undergo.

Even when your result is negative, you must undergo regular testing for STDifyou are not in a mutually monogamous relationship but sexually active. The average frequency for screening STD is once a year, but if you have more sexual partners, you may need more frequent testing.

Running one urine test for STD does not cover you for the entire year. A sexual encounter immediately after the test can get you infected. This will demand another STD test in London.

Urine testing for STD vs other STD tests

Many people still question the accuracy of a urine test for bacterial STDs like bacteria and gonorrhoea. This doubt is usually aboutsensitive cases. We understand the reason for this discontentment, and here is why:

The cervix is the most common site of sexual infection for women, and this is not the pathway for urine for women. Unlike men, the urine passes through the urethra, and it is easier to believe that the urine will pick some of the bacteria for the test.

Considering a study in 2015 that compared the testing methods for gonorrhoea and chlamydia, it was discovered that:

  • Out of the methods of testing for chlamydia in women, urine testing had 87% sensitivity and 99% for specificity compared to the cervical sample.
  • Out of the methods of testing for chlamydia in men, urine testing had 88% sensitivity and 99% for specificity compared to the urethral sample.
  • Out of the methods of testing for gonorrhoea in women, urine testing had 79% sensitivity and 99% for specificity compared to the cervical sample.
  • Out of the methods of testing for gonorrhoea in men, urine testing had 92% sensitivity and 99% for specificity compared to the urethral sample.

These results follow the same trend in many studies. But to our interest, we discovered that the vaginal swab collected by the individual patients had more effectiveness compared to the urine test or cervical swabs. Some women may prefer this method of testing to the cervical swab if urine testing is not available.,

Compared to vaginal and cervical swabs, urine testing detects fewer STDs than the cervical and vaginal swabs. However, science believes that urine is still working well by pinpointing many infected individuals.

This sounds great for people who prefer a less invasive method for testing of STDs. However, there may still be some level of invasion for some types of STD – which may include drawing out blood for a blood test.

Limitations of urine testing for chlamydia and gonorrhoea

Chlamydia and gonorrhoea are the two most common STDs in the UK. In 2017, there were 44,000 new cases of gonorrhoea announced. Majority of the cases were found in females ator below the ages of 25.

Men mostly have these diseases in the urethra and women in the cervix. This, however,are not the only locations of the infection. It can also occur in the throat if the victim engaged in oral sex or the rectum in the case of anal sex.

You should know that a urine test will not be able to detect the bacteria for oral and rectal cases. So, tell your doctor if you have oral and anal sex.

Also, men that have sex with fellow men should run regular urine testing, urethral, and throat swab like those who sleep with women. Those who only engage in vaginal intercourse can use urine testing alone for gonorrhoea and chlamydia.

Other STD tests with urine

The most prevalent STDs tested with urine is gonorrhoea and chlamydia. This is not all; the others include:


This infection isprevalent and can be diagnosed through urine testing. This method is gaining popularityin use,just like it is for chlamydia and gonorrhoea. Like the infections mentioned above, trichomoniasis is common and curable.

The urine testing for this disease is effective though not like the vaginal swab. The vaginal swab produces more sensitive results than urine.


Like trichomoniasis, human papillomavirus (HPV) is ubiquitous and can be detected through urine tests. This test is more sensitive when the first void urine is used for testing.

This test has the same challenge with other tests for HPV. The virus usually clears off on its own,but this is not where the problem lies. HPV is responsible for many cervical cancer cases because it causes problematic changes in the cervix. So, you should check for cervical changes rather than running the test. Thes changes in the cervix can only be determined by VIA test and Pap smear.


Urine test is not commonly used for testing herpes, syphilis and other STDs. Blood and oral samples are usually preferred compared to the urine. There are even home testing kits that use saliva samples to test for HIV.
