This of course will depend on various factors and will be discussed in your appointment.

Furthermore, we use PCR technology when looking for the DNA of the virus. This means that even the smallest amount of virus can be detected from the sample making it a highly reliable and useful test.

The Process

If you want to skip the consultation and just have the test, you can try our Drop & Go service.


In order to be most prepared and leave plenty of time for questions & discussions, we will ask you to fill out a simple questionnaire.


We will begin by assessing your medical & sexual history, any symptoms you may be experiencing and discuss any questions you may have.

Unlike most private clinics, we have medical consultants here to help you navigate through such problems and get you on the right track in no time.

Frequently Asked Questions

About The Test

How do you test for Chlamydia?

A Chlamydia test is done using a high vaginal swab in women, or a urine sample in men. Both men and women are able to have an additional oral or rectal swab, depending on if it is appropriate.

The test is run using PCR technology to test for the presence of the infection.

When should I get tested for Chlamydia?

You should get tested for Chlamydia if:

  • You are experiencing symptoms, or have known exposure (such as being a close contact of someone recently infected with Chlamydia.
  • You are pregnant or looking to become pregnant.
  • You have had unprotected sex with a new partner who has not been recently tested.
  • You have multiple partners or change your partners frequently.
  • You or your partner have had unprotected sex with another person.

Will I need a physical examination?

A physical examination may be recommended if you are presenting symptoms.

It is important to remember that physical examinations will only go ahead with your consent, and you are able to have a chaperone in the room to make you feel comfortable.

How can I prepare for my Chlamydia test?

  • Try to remember (as much as possible) the details of why you are visiting. For example, if you are showing symptoms, try to remember when these started and the potential cause of exposure.
  • If you are a male, please hold your urine for 1-2 hours before your appointment.
  • Relax, Clarewell Clinics is a safe space.

You can read more about Chlamydia treatment here.

Do I have to tell my partner if I test positive for Chlamydia?


Chlamydia is a very easy infection to pass on so we strongly advise that you inform your current partner(s) to be treated and tested. It is also advised that you inform any other sexual partner(s) from the last 6 months that you have the infection, so that these people can also get tested and treated. This breaks the chain of infection and prevents it from spreading to others.

Can I get a certificate of my Chlamydia test results?


Along with a text or email of your Chlamydia test results, we can email a certificate for official purposes. If you require a certificate please bring a form of ID with you to your appointment.
