Positive chlamydia even with condom?

Dear Doctor,

My husband cheated me by having sex with "pro". He had oral sex without condom and sex with condom. He went to take STD test on the next day. He has positive chlamydia but negative for herpes & HIV.  

I was told that it is very unlikely that someone using condom will infected chlamydia. His result as below:-

Result:2.7
Negative:1.1

Is there any possibility that it was false positive? We had unprotected sex two day after he had with "pro". I have done the test a week after and my result is negative. I wonder why?

Thank you.

This was already discussed on the std forum. It is possible either of you got a false result. If you haven't taken any medication yet, then both of you should retest. It should be conclusive at this point. If you were treated, then you will not likely be able to get an answer to your question.
