Chlamydia can usually be detected about 1 to 2 weeks after exposure, though symptoms (if they appear) often show up later, typically 1 to 3 weeks after exposure. Many people with chlamydia have no symptoms at all, so testing is important if there was potential exposure or you’re in a higher-risk group. If you’ve had unprotected sex or sexual contact with an infected person, consider testing around 2 weeks after exposure for the most reliable early result, and again later if symptoms occur or exposure continues. If you’d like, I can help interpret test timing for specific scenarios or help you find local testing resources.
