Chlamydia (Chlamydia trachomatis): Testing and Treatment in London

Private chlamydia testing and treatment at 101 Harley Street. Same-day or next-day results. Expert, confidential and non-judgemental care from Dr Dan Wright.

Chlamydia is the most commonly diagnosed bacterial sexually transmitted infection in the United Kingdom. It is caused by the bacterium Chlamydia trachomatis and is particularly common in sexually active adults. Despite its prevalence, chlamydia is frequently overlooked because the majority of infected individuals experience no symptoms whatsoever. Without testing, it is entirely possible to carry and transmit the infection without being aware of it.

At The Wright Practice, 101 Harley Street, we offer confidential, expert testing and treatment for chlamydia and a full range of sexually transmitted infections. For a broader overview of our sexual health services, see Sexual Health and for information on comprehensive screening, see Comprehensive STI Screening For information on gonorrhoea, which frequently co-occurs with chlamydia, see Gonorrhoea (Neisseria gonorrhoeae)

How Is Chlamydia Transmitted?

Chlamydia is transmitted primarily through sexual contact. The infection does not require penetrative intercourse to be passed on and can be transmitted during:

  • Vaginal sex
  • Anal sex
  • Oral sex
  • Genital-to-genital contact

The infection can affect a number of anatomical sites, including:

  • The urethra
  • The cervix
  • The rectum
  • The throat
  • The eyes (rarely)

Because chlamydia can infect sites outside the genital tract, urine testing alone is not always sufficient. Where oral or anal contact has occurred, additional swab testing of the throat or rectum may be recommended. Your clinician will advise on which sites require testing based on your individual history.

Symptoms of Chlamydia

The majority of people with chlamydia experience no symptoms at all. This is one of the primary reasons the infection remains so common. When symptoms do occur, they may develop days to weeks after exposure.

Book Consultation

Symptoms in people with a penis

  • Pain or burning sensation when passing urine
  • Urethral discharge, which may be clear, cloudy or white
  • Discomfort or swelling in the testicles
  • Pelvic or lower abdominal discomfort
Book Consultation

Symptoms in people with a vagina

  • Unusual vaginal discharge
  • Bleeding between periods
  • Bleeding after sexual intercourse
  • Pelvic pain or lower abdominal discomfort
  • Pain during sexual intercourse
  • Burning sensation when passing urine
Book Consultation

Symptoms of rectal infection

  • Rectal discomfort or pain
  • Rectal discharge
  • Rectal bleeding

Throat infections with chlamydia are generally entirely asymptomatic. The absence of symptoms does not mean an infection is absent. Testing is the only reliable way to know.

How Is Chlamydia Tested?

Modern chlamydia testing uses highly sensitive molecular techniques known as PCR (Polymerase Chain Reaction). PCR testing is extremely accurate and can detect the genetic material of Chlamydia trachomatis directly from a sample. This method is considerably more sensitive than older culture-based techniques.

Depending on which anatomical sites may have been exposed, testing may involve:

  • A urine sample (for urethral infection)
  • A self-taken or clinician-collected vaginal swab
  • A cervical swab, taken during examination when clinically indicated
  • A rectal swab, recommended when there has been receptive anal intercourse
  • A throat swab, recommended when there has been oral contact

When Should I Test for Chlamydia?

Testing too soon after a potential exposure may occasionally produce a false-negative result, because the concentration of bacterial DNA in the sample may not yet be sufficient for detection. As a general guide, testing is most reliable from approximately two weeks after a potential exposure, though earlier testing can still be informative.

Where there has been a very recent exposure, your clinician can advise on the optimal testing window and whether a repeat test at a later date would be recommended to provide greater reassurance.

Potential Complications of Untreated Chlamydia

When diagnosed and treated promptly, chlamydia is straightforward to manage and complications are uncommon. However, when left untreated, the infection can cause significant health problems over time.

Book Consultation

Complications in people with a uterus and fallopian tubes

  • Pelvic inflammatory disease (PID), an infection of the upper reproductive tract
  • Chronic pelvic pain
  • Damage to the fallopian tubes, which can affect fertility
  • Increased risk of ectopic pregnancy
Book Consultation

Complications in people with testes and epididymis

  • Epididymitis, an inflammation of the epididymis
  • Testicular pain and swelling
  • Chronic discomfort

These complications can generally be avoided entirely through early diagnosis and treatment. Routine screening is therefore far preferable to waiting for symptoms to develop.

Book Consultation

How Is Chlamydia Treated?

Chlamydia is generally straightforward to treat with a course of antibiotics. Treatment is highly effective when taken as directed. The specific antibiotic used and the duration of the course will depend on the site of infection and individual patient factors, and your clinician will advise on the most appropriate regimen.

Following treatment, it is important to avoid sexual contact until the course of antibiotics has been completed and, where relevant, until partners have also been treated. Sexual partners may require testing and treatment themselves to prevent reinfection. Your clinician can advise on partner notification and how best to approach this.

A test of cure, a repeat test to confirm that treatment has been successful, may be recommended in certain circumstances. For co-infection with gonorrhoea, which is not uncommon, see Gonorrhoea (Neisseria gonorrhoeae) and Gonorrhoea

Frequently Asked Questions

Can I have chlamydia without any symptoms?

Yes. The majority of people with chlamydia, estimated at around 70 to 80 percent, experience no symptoms at all. This is precisely why routine testing is so important. You can carry and transmit chlamydia without knowing, and the only reliable way to find out is through testing.

How soon after exposure should I get tested?

Testing is generally most reliable from around two weeks after a potential exposure. Testing earlier than this may occasionally produce a false-negative result. If you have had a recent exposure, your clinician can advise on the most appropriate timing and whether a repeat test would be recommended.

Do I need to test from multiple sites?

This depends on the type of sexual contact you have had. If oral or anal contact has occurred, swabs from the throat and/or rectum may be recommended in addition to genital or urinary testing. Relying on urine testing alone may miss infections at these sites. Your clinician will advise on which samples are appropriate.

Will my chlamydia result affect my medical records or be reported?

At The Wright Practice, all consultations are confidential. Your medical records are private. Your results will not be shared without your consent, and our approach is always one of discretion and respect.

Can I be reinfected with chlamydia after treatment?

Yes. Treatment clears the current infection but does not provide ongoing immunity. Reinfection is possible if you have sexual contact with a partner who has chlamydia. This is why partner notification and treatment is important, and why routine follow-up testing is recommended for those with ongoing exposure risk.
