Hello, so i tested positive for chlamydia and was treated with doxy for 7 days and am now wondering how soon i can retest for toc? i know normally you would retest 3-4 weeks but my new partner wants a negative test first before any sexual activity?

You can retest in two weeks or follow the usual period and in the meantime try to convince your new partner to try with a condom or other ways to have sex- or wait till after the test.

Three weeks is the minimum time for test of cure. Even with successful cure, chlamydial DNA can persist and give a false positive test result for up to 3 weeks. On the other hand, doxycycline never fails to cure chlamydia when taken properly (100 mg twice daily for 7 days with few or no missed doses). So if you took the drug as directed, you're safe having sex once you have finished treatment.
