Chlamydia Trachomatis (Urine)
Does this test have other names?
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 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 can get endometriosis later on.
Chlamydia can be effectively treated with antibiotics.
