Does this test have other names?

No.

What is this test?

This test looks for Chlamydia trachomatis bacteria in a sample of cells collected by your healthcare provider.

C. trachomatis bacteria cause chlamydia. Chlamydia is the most common sexually transmitted disease (STD) in the U.S.

The CDC recommends that sexually active women 25 and younger, as well as older women with risk factors, be screened once a year for chlamydia. That's because as many as half of women who get chlamydia don't have any symptoms. Men should be tested as soon as they have symptoms or if their partners are diagnosed with chlamydia.

In women, chlamydia may lead to cervicitis, an inflammation and swelling of the cervix. If it isn't treated, it can lead to serious sexual health problems, including infertility. In men, chlamydia can cause urethritis. This is a swelling of the urethra and possibly blood in the urine. Babies born to infected mothers can get pneumonia or conjunctivitis. The mothers may also develop endometriosis.

Chlamydia can be effectively treated with antibiotics.

Why do I need this test?

You may need this test if you are a sexually active woman 25 or younger, older women with risk factors such as new or multiple sexual partners, or a man whose partner has been diagnosed with chlamydia. 

When symptoms happen in women, they can include:

• Abnormal vaginal bleeding or discharge

• Stomach pain

• Pain during sex

• Pain when urinating

• Rectal pain

When symptoms happen in men, they can include:

• Watery discharge from your penis that's not urine

• Pain when urinating

• Swollen scrotum

• Painful sensation in your testicles

• Rectal pain

What other tests might I have along with this test?

Your healthcare provider may also order other tests because chlamydia symptoms can be confused with symptoms of other STDs. These STDs include:

• Gonorrhea 

• HIV/AIDS

• Hepatitis B

• Trichomoniasis

• Syphilis

What do my test results mean?

Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. 

Normal results are negative, meaning that no chlamydia cells were found in your urine.

A positive result means that chlamydia bacteria were found and that you are likely infected with the disease.

How is this test done?

This test needs a "first void" urine sample: You will collect your first urine in the morning after you wake up.

Does this test pose any risks?

This test poses no known risks.

What might affect my test results?

Other factors aren't likely to affect your results.

How do I get ready for this test?

You don't need to prepare for this test. Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illicit drugs you may use.
