The CDC estimates that nearly 2 million people in the United States have chlamydia [1]. This sexually transmitted infection (STI) can spread rapidly since many people with chlamydia don't realize they have it.

That’s why it’s important to know how to test for chlamydia. (The Everlywell Gonorrhea & Chlamydia Test allows you to test in the privacy of your own home. If you receive a positive result from this at-home chlamydia test, you have the option to connect with a physician in our network who may prescribe medication.)

Read on to find out more about chlamydia testing—plus who is at risk for infection, symptoms, and more.

What is chlamydia?

Chlamydia is caused by Chlamydia trachomatis bacteria [2], which spread through anal, vaginal, or oral sex. Both men and women can be infected with chlamydia.

Many people confuse chlamydia with a gonorrhea infection. Both infections are caused by bacteria and are spread through sexual contact. The Everlywell at-home test checks for both gonorrhea and chlamydia bacteria.

Who is at risk for chlamydia?

Any sexually active person can become infected with chlamydia bacteria [3]. Younger people and people with several sex partners may be at a higher risk of contracting an STI, including chlamydia.

Additionally, mothers with STIs like chlamydia can transmit the infections to their babies [4]. If you're expecting a baby, speak with your healthcare provider for more information about chlamydia and gonorrhea test options.

Practicing safe sexual intercourse methods can help prevent the spread of many STIs, including chlamydia. Using condoms can reduce your risk of contracting the infection. However, you can still get chlamydia even if you take precautions. Routine STI tests are important for anyone who is sexually active.

If you are experiencing symptoms of gonorrhea or chlamydia, it may be a good idea to get tested as soon as possible (and speak with your healthcare provider).

Many people put off getting tested until they develop symptoms. But keep in mind that chlamydia is often asymptomatic [5]. Even if you feel healthy, you might carry a chlamydial infection and pass it on to others. Knowing your STI status is important to help you and your sex partner (or partners) avoid infection. With our Chlamydia and Gonorrhea Test kit, it’s easy to get tested from the comfort and privacy of your home.

What are the symptoms of chlamydia?

Chlamydia symptoms can vary between women and men [6].

Women may experience:

  • Abnormal vaginal discharge
  • Pain during intercourse
  • Abdominal or pelvic pain

Men may notice:

  • Discharge from the penis
  • Burning or itching around the penis
  • Painful or swollen testicles

Both men and women may have other symptoms, including:

  • Rectal pain, itching, or bleeding
  • Pain while urinating
  • Fever

Because people with chlamydia don’t always have symptoms, it’s important to test for STIs (with a gonorrhea and chlamydia home test kit, for example) to know your status. (Read more on how to test for STDs, including where to get an STD test and the sample types that are used.)

How to get tested for chlamydia

If you're wondering how to test for chlamydia safely, here are several ways you can do so. Depending on your medical history and health concerns, your healthcare provider may suggest more than one test to see if you have a sexually transmitted infection. A panel might require a blood sample, genital swab, or urine sample.

While chlamydia isn't a bloodborne disease, blood tests can determine whether you have chlamydia antibodies, which can reveal current or past chlamydia infections.

A penile or vaginal swab is another method your healthcare provider may use to test for STIs. For this type of test, your doctor uses a cotton swab for specimen collection.

Can you test for chlamydia through urine? The answer to this question is “yes,” and it’s quite a common testing method. In fact, you can use a urine sample to test for chlamydia at home. With the Everlywell Chlamydia & Gonorrhea Test, you simply urinate in a collection cup and place your urine specimen in the mail. Your sample is then tested in a CLIA-certified laboratory. The lab that tests your sample uses molecular testing techniques—known as nucleic acid amplification tests—which identify the DNA of gonorrhea and chlamydia in your sample.

What if my results are positive?

The Everlywell Chlamydia & Gonorrhea test includes an easy-to-understand lab report. But if you're not sure how to read your chlamydia test results, your healthcare provider can help.

A positive STI test result can be unsettling, but you aren’t alone: with the Everlywell Chlamydia & Gonorrhea Test, you have the opportunity to speak with a physician in our network to discuss your results further if you test positive—and you may be prescribed medication.

If your chlamydia test is positive, STI testing is recommended for your sex partner(s) [7]. If they are infected and don't receive treatment, they can pass the chlamydial infection back to you.

Common questions

Am I at risk for chlamydia?

You may face an increased risk of chlamydia (and other STIs) if you have unprotected sex or have multiple sex partners. However, there are other risk factors besides these, so talk with your healthcare provider if you want to know more about your risk and what it could mean for your sexual health. And don’t forget: when it comes to prevention and risk-reduction, regular STI screening can be a great place to start.


Should I get a chlamydia test?

It can be a good idea to screen for chlamydia and other STIs if you’re considering having sexual intercourse with a new partner. If you believe you have been exposed to chlamydia or are experiencing symptoms (like pain, itching, or swelling around your genitals), consider screening for infection by visiting a local clinic⁠—or take a chlamydia test at home.

Also, according to the CDC, if you're a sexually active woman younger than 25, you should test for chlamydia and gonorrhea at least once a year [8]. You should also get tested yearly if you're 25 or older and have risk factors like new or multiple sex partners. The CDC also recommends annual gonorrhea and chlamydia testing for gay and bisexual men.


Can chlamydia affect my fertility?

A chlamydia or gonorrhea infection may cause inflammation or scarring of the reproductive organs. Sometimes, this may lead to infertility [9]. Both men and women can experience fertility problems after a chlamydia infection. Your risk of infertility increases if you delay treatment.

Women with untreated gonorrhea or chlamydia can also develop a condition known as pelvic inflammatory disease (PID) [10]. PID sometimes causes your reproductive organs to swell, triggering chronic pelvic pain and making it difficult to conceive.

Chlamydia and gonorrhea can also trigger early labor—and pregnant women with chlamydia can spread the infection to their babies during delivery [11]. (Find out more about STDs in women)

Prompt treatment reduces your risk of complications, as undiagnosed chlamydia may put your health at risk. Regular STI testing can help with early diagnosis of the infection, and most people who receive treatment for chlamydia make a full recovery.
