What is this test?
This test screens for Chlamydia trachomatis, a common bacterial infection of the reproductive tract. The laboratory may detect the organism's genetic material or other evidence of infection, depending on the specimen and testing method used.
Why might I need this test?
Screening may be recommended for people who are sexually active, especially younger adults or those with a new partner or multiple partners. It is also commonly included in routine preventive care because chlamydia often causes no noticeable symptoms.
How is the test performed?
A healthcare professional collects a specimen according to the type of screening test ordered. The laboratory then checks the specimen for evidence of Chlamydia trachomatis using an approved testing method.
How do I prepare for the test?
Follow the specific collection instructions provided by the healthcare professional or laboratory. Preparation requirements vary by specimen and may include avoiding urination or other activities for a short period before collection.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result suggests that chlamydia may be present and should be reviewed with a healthcare professional. If confirmed, the infection can usually be treated with antibiotics, and sexual partners may also need evaluation and treatment. A negative result lowers the likelihood of infection, but repeat testing may be appropriate if exposure was recent or symptoms continue.
