Gonerhea test and treatment

Hello all! Thanks for reading.

After a brief encounter and being at risk for chlamydia as they tested positive I took doxy as a precaution.

2 days after treatment ended I took an oral swab for Gonerhea to rule that out and it since came back negative.

1. Exposure to potential Gonerhea at time if test was 4 weeks and 2 days after doxy.

I know doxy is not used to treat Gonerhea but what are the risks it MAY result in a false negative if any?

Should I stop worrying....

Many thanks you lovely people

Hi there,

First of all, what was your exposure?

Also if a partner tested for positive for chlamydia its likley they did the "full" STI panel which includes


You didnt mention if the chlamydia was oral or not which changes the testing method but that being said, if your partner did the whole panel and only chlamydia came up then it is safe to say they did not have gonorrhoea which means you do not either.

If you tested 4 week after the antibiotics then that result should be accurate.

Appreciated but i think you misread slightly...

I guess what im after is the answer to the following:

Would testing for G by swab, 2 days after a 7 day course of doxy (4 weeks after initial contact exposure) give a false negative?  

Many Thanks
You should test at least 2 weeks from finishing the course of antibiotics. But my original comment remains... If your partner did a test for STIs and gonorrhoea didnt show up, then you wont have it. What was the risk?
I get what your saying but I can't be certain with her. The course was for risk of chlamydia not gon...so would it matter?

Doxy wouldn't clear gon...so would it impact a swab test?
Yes, it could give you a false negative. It could kill enough of or slow the growth of the gonorrhea enough to give you a false negative. That's why SIllyMistake suggested waiting 2 weeks after you finish your doxy.

We can help you more if you tell us your risk.

It was from preforming Oral on a female briefly and kissing with tongue...

I know it's low risk but, there's always a but...

I thought doxy, as not used for G treatment wouldn't affect my test results for that specific test :(
The chances of getting anything from that exposure is so so low its mental.
In your opinion why do all professional med centres or places if service say its a risk? Honestly curious...
im not sayings its not a risk. crossing the road is a risk. But it is a small one. Ill explain it logically...

The bugs tend to live deeper. In the mouth they live in the throat, penis they live within the urethra and they live deeper in the vagina, not on the lips.

The bugs are quite fragile and the living conditions need to be good - otherwise they die. They also do not like saliva due to enzymes which kill them off. So look at it like this.

You gave oral sex to a girl. Usually you would stay around the outside/lips of the vagina. Say you did go deeper and got one of the bacteria on your tongue the chances are the saliva and the air would kill it off WAY before it got to your throat. Even if it did get back there it would be break and highly unlikely to grab hold.

Thats the simple version.

Thanks, so key question...should I retest again or just move on with my life.

Only thing concerning me is I have this low level, sinus type headache for the past week. Makes me think infection, Gonerhea etc.
personally I would move on from this. It is the time of year with the weather changes where there are so many coldy things. Also Gohno tends to cause more of a sore throat and doesnt play in the sinuses :)
I totally agree with this.

And while doxy doesn't cure gonorrhea, it can slow the growth of gonorrhea enough that it could give you a false negative. They say that for doing any kind of testing for bacteria, it's always preferable to be off antibiotics for 2-3 weeks.

This is so incredibly low risk I wouldn't worry at all.
