false positive chlamydia test

[terry333]

I had a papsmear and GC test done recently. After a week the result came back. Clamydia (chlamydia) result was positive (sample taken from my cervix). I told my provider that the lab made a mistake and wanted to be retested. There is no way I would have gotten a clamydia (chlamydia) for the following reasons. 1) last year's clamydia (chlamydia) was negative 2) I did not have sex for about a year and to the time recent STD testing done. 3) My husband and I are faithful and truthful with each other.  My provider encouraged I get treated right away but I insisted I wanted to be retested before anything else. She ordered that I provide a urine sample to be tested for chlamydia first thing in the morning. I did. RESULT CAME OUT NEGATIVE this time!   My concern is, she ordered that I take flagyl BID for a week when she did my pap (I think she was concern of the discharge). When I did my urine test for chlamydia I just finished the course of antibiotic she prescribed. Will it affect the clamydia (chlamydia) testing? I am confused.  Moreover, my provider wanted another testing this time despite that result already is NEGATIVE. She said that a sample taken from my cervix will be more reliable than the urine she just ordered. In the first place, why did she ordered a urine test when I asked her to be retested?

Your antibiotic use could be causing a false negative.  Flgayl wouldn't cure the chlamydia, but could inhibit the growth of it enough to give you a false negative test.

Personally, until you've been off those antibiotics for 2 weeks, I wouldn't trust a negative result.

The swab test MIGHT be more accurate because it would even pick up dead chlamydia dna.

One way to solve this, or at least help, is to have your husband test.

If you come back positive, then he is going to need to test and treat, so why not have him just do it now?

Oh but you need to wait 2 weeks from the last flagyl to test with a swab, too.

I would suggest retesting with a cervical swab using the Gen-probe test. Ask your doctor about this. I agree with Auntiejessie`s response. Take care.

Gen-probe!  Thank you!  I had been wracking my brain when I wrote this for the name of that test, and couldn't remember for some reason.  Thanks for helping, even though you didn't know you had to.  :)
