A false chlamydia test result can come from any of these factors:
- Urination less than a few hours before urine testing.
- Poor technique for swabs
- Not disclosing the possible location of infection (e.g. if you only have receptive anal sex, then urethral testing won't find your infection).
- Recent antibiotics that reduced, but didn't eliminate, chlamydia infection
- Testing too soon after infection.

You might have gotten chlamydia from somewhere else, you could have some other infection, your partner could have had a false negative result, or you might have some other non-infectious problem.
