Biomarkers
Chlamydia
Chlamydia is a common sexually transmitted infection (STI) that, if left untreated, can lead to serious health complications over time, such as infertility or pelvic inflammatory disease. It is highly transmissible, meaning if you’re infected without knowing, you could unknowingly spread it to your sexual partners, putting them at significant risk. Regular testing and early treatment are crucial to prevent long-term health issues and reduce transmission.
Trichomoniasis
Trichomoniasis is an infection caused by the parasite Trichomonas vaginalis. It can lead to symptoms such as itching, burning, and unusual discharge, though many people infected with the parasite may not experience any symptoms. It’s important to get tested regularly, as untreated trichomoniasis can lead to complications and increase the risk of spreading other STIs.
Gonorrhoea
Gonorrhoea is a sexually transmitted infection caused by the Neisseria gonorrhoeae bacteria. It can affect various parts of the body, including the urethra, rectum, throat, and cervix. Symptoms may be mild or even absent, making it easy to unknowingly spread the infection. If left untreated, gonorrhoea can lead to serious complications, such as infertility, pelvic inflammatory disease (PID), or an increased risk of HIV transmission. Regular testing and prompt treatment are crucial to prevent long-term health issues.
Mycoplasma Genitalium
Mycoplasma genitalium (Mgen) is a bacteria that can be sexually transmitted and affects individuals of all genders. It is known to cause sexually transmitted infections (STIs) and can lead to several reproductive and urinary system issues, such as pelvic inflammatory disease (PID) in women and urethritis in men. Many people with Mgen may not show symptoms, which increases the risk of undiagnosed transmission. Early detection and treatment are important to prevent complications.
Information
Symptoms
Over 80% of sexually transmitted infections (STIs) are asymptomatic, with many, like chlamydia, often showing no symptoms. This makes regular testing and prompt treatment essential for maintaining sexual health and preventing complications.
Common symptoms of STIs may include:
- Pain when urinating
- Painful erections (in males)
- Pain and discomfort around the vaginal area (in females)
- Pain during sexual intercourse
- Discharge from the genitals
- Rashes on the genital or anal area
- Strong vaginal odours
- Unusual lumps or blemishes around the genital area
Additional Information
Chlamydia Test
Chlamydia is a sexually transmitted infection (STI) that can lead to serious health issues if left untreated, but it can be easily treated with antibiotics.
If you think you might have chlamydia, it’s important to get tested as soon as possible. Testing can be done at your local health center, doctor’s office, or with a home test kit.
Types of Chlamydia Tests:
- Urine Test: This test checks for chlamydia bacteria in your urine.
- Swab Test: A sample of discharge from the vagina or penis is collected to check for the infection.
Both tests are quick, easy, and usually provide results within a few days. If your test comes back positive, chlamydia can be effectively treated with antibiotics, typically taken for 7-10 days. It’s essential to complete the full course of antibiotics, even if you start feeling better, and to avoid sex until the treatment is finished.
Why Testing Is Important:
Chlamydia is a common STI caused by Chlamydia trachomatis. It can infect both men and women and is typically spread through sexual contact. It can also be passed from an infected mother to her baby during childbirth.
If untreated, chlamydia can cause permanent damage, particularly to a woman’s reproductive organs, leading to infertility or complications during childbirth. In newborns, untreated chlamydia can lead to serious infections of the brain and spinal cord.
Regular Testing and Prevention:
If you’re sexually active, it’s recommended to get tested for chlamydia annually, especially if you have new or multiple partners. Regular testing can help prevent complications and ensure that the infection is treated early.
If you test positive, it’s important to inform your sexual partners so they can get tested and treated as well. Untreated chlamydia can result in infertility, arthritis, and other severe health issues.
Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert
Chlamydia is often passed on unknowingly because many people infected with the bacteria show no symptoms. This makes it easy for sexual partners to transmit the infection without realizing they have it. If left untreated, chlamydia can lead to serious health complications. For women, it can progress to Pelvic Inflammatory Disease (PID), which can cause severe pain, long-term health issues, and fertility problems. Pregnant women with chlamydia can also pass the infection to their babies, potentially leading to serious health issues for the newborn, including eye infections and pneumonia. Regular testing and prompt treatment are crucial to prevent these complications.

FAQs
What happens if you test positive for chlamydia?
If you test positive for chlamydia, your doctor will prescribe antibiotics to treat the infection. It’s important to take the full course of antibiotics as prescribed to fully cure the infection. You should avoid sex until both you and your partner have completed the treatment.
Why should you get tested for chlamydia?
Chlamydia is a common STD that can be easily cured with antibiotics. If left untreated, it can lead to serious health issues, including infertility in women.
If you are sexually active, it’s important to get tested for chlamydia and other STDs annually or more frequently if you have multiple partners.
If you experience symptoms of chlamydia, such as burning during urination or abnormal discharge, you should see a doctor and get tested immediately. Early treatment can prevent complications and promote better health.
Where do I send my sample?
You will receive a free return label to send your health test samples back to the lab. Clear instructions with return information will be provided via email.
What do I need to do before my test? i.e. fast, no drinking, etc
If fasting or limiting alcohol intake is required before your blood test, we will send you personalized instructions via email after your order is placed. However, most tests can be taken without the need for fasting.
When will I get my results/how will I receive my results?
Results are typically processed within 2–3 working days. If a sample is sent over the weekend (which we do not recommend), you will receive your results within 2–3 days from the following Monday. Once your results and personalized report are ready, you will receive an email notification with instructions to log in to the Welzo online platform and view your results.
How soon can you detect chlamydia?
Most tests can detect chlamydia within a week of exposure.
If you experience symptoms such as burning during urination or abnormal discharge from the penis or vagina, it’s important to see a doctor right away and get tested. Early detection and treatment can prevent serious health complications.
How do tests detect chlamydia?
There are two main types of tests used to detect chlamydia: nucleic acid amplification tests (NAATs) and enzyme-linked immunosorbent assays (ELISAs).
-
NAATs are the most sensitive and specific tests for chlamydia. They can be performed on urine samples or swabs from the urethra in men or from the cervix, vagina, or rectum in women.
-
ELISAs are less sensitive and specific than NAATs but can also be performed on urine samples. While they may be convenient, NAATs are generally preferred for their higher accuracy.
What if my results show that I’m outside the normal range?
If your results fall outside the normal range and are concerning, it is crucial to contact your local GP or emergency service immediately by calling 111 or 999. Please remember: If you feel unwell or are worried about your health, it is your responsibility to seek medical attention promptly, without waiting for results.
Disclaimer: If your test results are abnormal, we are not responsible for follow-up treatments or notifying a healthcare professional. By taking a test with us, you agree to take the necessary steps to follow up with a healthcare provider independently.
