Test results conclusive?

[SunnyTH]

Dear Doctor,

I am from Thailand, (sorry for my bad English language) I did have a sex 1 year ago (Dec 6, 2012) with a commercial sex worker and using protected vaginal by condom and then it did not break or fail. After that, I have tested at Hospital by following information.

- 1st; Feb 5, 2013 (CMIA method: Negative)
- 2nd; July 14, 2013 (ELISA method: Negative)
- 3rd; Sept 28, 2013 (ELISA method: Negative)
- 4th; Oct 24, 2013 (CMIA method: Negative)  

But, I still concern and worried about windows period and the infection issue; I would like to ask you about the following.

- What are my chances of being infected with HIV? How long should I wait until being tested?

- In some resource in Thailand (Website) it says that for some people it takes 6 months and even 12 months for an immune response, how can one know about this.

- Can I confident about conclusive of my test results?

Please kindly advise me? Thank you very much.

Best regards,

Sunny

Hi Teak, Thank you very much for your answer. :)

You had protected sex and didn't have an exposure nor did you need testing.
