Chlamydia Tests

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

  • Stool with the rectal sample.
  • Using antibiotics before the test.

What To Think About

  • If a chlamydia infection is suspected, do not have sexual intercourse until the test results have come back. If you have a chlamydia infection, do not have sexual intercourse for 7 days after the start of treatment. Your sex partner(s) should also be treated for a chlamydia infection so that you don't get reinfected and so that others don't get infected.
  • Only one laboratory test (NAAT, ELISA, DFA, DNA probe testing, or chlamydia culture) is needed to diagnose chlamydia. Your doctor can choose which test to use.
  • Your doctor is required to report your chlamydia test result to the state health department. The department may contact your sex partners to inform them that they also need treatment.
  • Screening for and treating chlamydia can help prevent pelvic inflammatory disease (PID). To learn more about the treatment of a chlamydia infection, see the topic Chlamydia.
  • Other sexually transmitted infections may be present at the same time as chlamydia. So it is important to be tested and treated for all STIs. Chlamydia as well as other STIs can also increase the chance of getting human immunodeficiency virus (HIV). An HIV test may be offered at the same time as a test for chlamydia or other STIs.
