Can you get a false positive on a chlamydia test while being on biaxin (clarithromycin) antibiotics? Tk u dr!

Nope: Clarithromycin (Biaxin®) cannot make a chlamydia test falsely positive. If you have a positive test while taking the drug, it means you have (or had) chlamydia. After cure of chlamydia with antibiotics, it takes 1-2 weeks for the test to become negative. However, clarithro has not been studied much against chlamydia. For more reliable treatment, ask your doc about azithromycin or doxycycline. ...Read more

In those instances you can test to make sure that you are disease-free at 3 weeks after treatment. Also you should be treated for Gonorrhea as this can coexist with the Chlamydia infection.

After finishing chlamydia treatment of Doxycycline, can I get retested without a false positive 1-2 weeks after?

Too soon: Retesting probably isn't necessary at all. Doxycycline never fails to cure chlamydia, if taken as directed (usually 2x daily for 7 days). But if you would feel better with a repeat negative test, wait until 3 weeks. Earlier tests can be false positive, because chlamydial DNA persists for up to 3 weeks after cure. It's more important to be retested after 3-6 months, because reinfection is common. ...Read more

Good evening doctor. My partner of 4 years and I recently went to get tested for stds and he came up positive for chlamydia. I came out negative. He swears it's only been me for 4 years. Is there a possibility that the test could've been a false positive?

False Positive: No test is 100%. There will be false positives and false negatives. You can always get another test. That being said, if you both have been monogamous for the past 4 years why the tests? Just food for thought. Additionally, if you have had antibiotics recently it could gave cured any infection you had. Remember men usually have no symptoms. ...Read more
