Sexual Health > Chlamydia Test
Chlamydia is the most common sexually transmitted infection in the UK. Predominantly, it is diagnosed in young people, but it also affects older people, with a growing number of people over 40 testing positive. In 2023, there were about 194,970 Chlamydia diagnoses (all ages).
Fortunately, chlamydia is treatable and curable with antibiotic tablets, such as azithromycin or doxycycline, when caught early. If you are concerned, our City Walk-In Clinics offer transparent pricing, exceptional care and treatment options, and maintain privacy and confidentiality at all times.
Chlamydia is a sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. It can infect and affect both men and women and can cause serious, permanent damage to a woman’s reproductive system, making it difficult or impossible for her to get pregnant later on.
Chlamydia can be diagnosed through laboratory tests such as urine samples or swabs from the genital area. Regular screening is recommended, especially for sexually active women under 25 and older women with risk factors like new or multiple sex partners.
Chlamydia is primarily transmitted through unprotected sexual contact, including vaginal, anal, and oral sex. It can also be passed from an infected mother to her baby during childbirth.
One of the challenges in controlling the spread of Chlamydia is that it often presents no symptoms, leading many individuals to be unaware of their infection and inadvertently transmit it to sexual partners.
Most people who have Chlamydia will not notice any symptoms. According to research, 50% of men and 70 – 80% of women will be asymptomatic when infected by Chlamydia. In some cases, you may show symptoms only briefly, but even if the symptoms disappear you may still have the infection and still be able to pass it on to others.
When symptoms do occur, they can include abnormal genital discharge, burning sensation during urination, pain during sexual intercourse, and in women, bleeding between periods or after sex. If left untreated, Chlamydia can lead to serious health complications, particularly for women, such as pelvic inflammatory disease (PID), ectopic pregnancy, and infertility. In men, untreated Chlamydia can lead to epididymitis, an inflammation of the ducts attached to the testicles, which can cause infertility.
Chlamydia can be diagnosed through laboratory tests such as urine samples or swabs from the genital area. We test for Chlamydia with Gonorrhoea by urine PCR or by swab. If you have no symptoms and are testing for peace of mind, there is no consultation fee payable.
However, if you have any symptoms, please note that a consultation fee of £85 applies for a specialist nurse or £175 for a GP. All prices are listed on our pricing page for full transparency. Remember, regular screening is crucial for prevention and early detection. Our team provides consistency of care and same-day appointments to help you receive the information (and treatment) you need as quickly as possible.
If you test positive for Chlamydia, take the full course of antibiotics as prescribed, even if symptoms disappear. Notify all recent sexual partners (anyone from the last three months) so they can get tested and treated.
Partners should be treated even if they have no symptoms to prevent reinfection and spread. Avoid all sexual activity until both you and your partner have completed treatment and are symptom-free for at least seven days after finishing antibiotics.
Get re-tested after three months to ensure the infection is cleared, especially if you are unsure whether your partner was treated or if you had unprotected sex.
Chlamydia remains a significant global health issue, with substantial numbers of new infections reported annually. In 2020, the World Health Organisation (WHO) estimated that there were 129 million new Chlamydia infections worldwide. This figure highlights the pervasive nature of this sexually transmitted infection (STI) across different regions and demographics.
In 2022, more than 1 million curable sexually transmitted infections, including Chlamydia, were acquired every day globally. This underscores the importance of getting tested for Chlamydia regularly.
Preventing Chlamydia involves several strategies aimed at reducing the risk of infection through sexual contact. Here are key measures to help prevent Chlamydia:

As an international visitor, I was very grateful for the prompt attention to my request for an appointment. Dr Ali was respectful and empathetic in regard to my condition and suggested further treatment, which I was able to organise for the next day. Both offices I attended treated me appropriately and I would recommend Harley Street Health Walk-in Clinics to anyone visiting London who requires medical attention.Posted on Trustindex![]()

Highly recommend City Walk-In Clinic Really pleased with my experience at City Walk-In Clinic. I booked a female hormone test because I wanted some answers about a few symptoms I'd been having, and the whole process was straightforward. The staff were welcoming, friendly and didn't make me feel rushed at all. The blood test was quick, and they explained everything clearly before taking the sample. My results came back sooner than I expected, and it was reassuring to have everything presented in a way that was easy to understand. I'd definitely use the clinic again and would recommend it to anyone looking for a private female hormone test. Professional service, lovely staff and an all round positive experience.Posted on Google![]()

I had a private gp appointment yesterday as my feet have been swelling every day over the past few days. So I booked an appointment with Dr Heather. Dr Heather explained the possible causes of the swelling, including the heat that we are currently experiencing in London. Recommended further investigation if the swelling persists, to identify the underlying issue rather than just making assumptions.Posted on Google![]()

I have used City Walk In Clinic as my go to place for routine blood tests. My recent full health check gave my doctor some clues that i may be approaching my menopause era. So my doctor has recommended that i do some tests to find out if indeed i am entering perimenopause, as the symptoms are there. Will be having my tests in the next few weeks. So glad i had a full health check, because all these symptoms were driving me crazy.Posted on Google![]()

I attended The Harley Street Walk/in centre in the City recently. I was able to book my appointment the day before for a blood test at a time that suited me. The booking process was straightforward. The doctor that conducted the venous draw was efficient and very pleasant. I have never had such a painless venous draw and I have had many! My appointment was at 5pm and I had my results before 8 am the following day. I will be very happy to book my tests here in the future. Thank you.Posted on Google![]()

I wanted a cholesterol check up and chose this clinic because it seemed to offer a competitive price for a detailed report. And so it turned out to be. Received a prompt and professional service at a price that was significantly less than other nearby providers in central London. I have now used it twice and would definitely recommend.Posted on Yell![]()

The Walk-In Clinic in central London exceeded my expectations in every way. Their attention to detail and commitment to tailored care for their patients truly sets them apart. The availability of evening appointments until 6:30 pm was a game-changer for someone like me juggling multiple commitments.Posted on Yell![]()
