Nucleic acid amplification tests (NAAT). These tests find the genetic material (DNA) of chlamydia bacteria. These tests are very good at identifying chlamydia. A test that is positive almost always means the problem is there and is unlikely to be a false-positive test result. A polymerase chain reaction (PCR) test is an example of a nucleic acid amplification test. This test can also be done on a urine sample.
Chlamydia culture. A culture is a special cup that allows the chlamydia bacteria to grow. Results take longer (5 to 7 days) than the other tests. The culture must be done in a lab.
Why It Is Done
A test for chlamydia is done to:
See whether symptoms of a sexually transmitted infection (STI) are caused by a chlamydia infection.
