Unprotected Oral and Protected Vaginal

[PeterLim]

Dear Doctor,

Please forgive my poor English

I had a unprotected oral and protected vaginal sex with a sex worker 9 weeks ago, I did went for a HIV screening test in hospital yesterday. They took my blood for testing and the result came out after 3 hours. The hospital called me and told me that the result was HIV Non-reactive with some figures like 0.12 or 0.012 (I cant really remember).



So this is my story and I hope to ask you some questions:

1) Which type of testing did the hospital perform most likely ?

2) Is my 9 weeks HIV negative test conclusive enough ?

3) Do I need to test again on week 13 ?

4) Have you ever seen any 9 weeks negative turn positive on week 13 ?

5) Assuming my penis had a small cut during the unprotected oral sex, what is the chance for me to get HIV?


Thanks and have a nice day Doctor

May God bless all of you !

Welcome to our Forum.  I'll be glad to comment.  The exposure that you describe was virtually no risk and had you asked, I would have you told you that your risk for HIV from this exposure is so low that you did not need HIV testing at all.  Having tested, you have now proven that you did not acquire HIV, as expected.  There is virtually no risk from condom protected sex if the condom was worn throughout the exposure and did not visibly break.  Also, there are no known cases in which someone has acquired HIV from receipt of oral sex from an infected partner, if your partner had HIV and it is unlikely that your partner did have HIV-most commercial sex workers do not.

As for your specific questions:
1) Which type of testing did the hospital perform most likely ?

It is difficult to say.  This could have been a standard HIV antibody test or a 4th generation, combination HIV antibody/HIV p24 antigen test.  Both tests take a few hours to run and provide similar numerical results.  Either way, your test results at 9 weeks are definitive and should be believed- they prove you did not get HIV from the exposure you mentioned.

2) Is my 9 weeks HIV negative test conclusive enough ?

Yes- see above

3) Do I need to test again on week 13 ?

there is no need for more testing

4) Have you ever seen any 9 weeks negative turn positive on week 13 ?

No, that is not a concern

5) Assuming my penis had a small cut during the unprotected oral sex, what is the chance for me to get HIV?

This makes no difference- still no risk

I hope these comments are helpful to you. EWH

Dear Doctor,

thanks for the quick reply.

However, I still have some questions.

1) Is the 9 weeks negative result conclusive enough regardless of any type of testing ?

2) which test is better among standard a HIV antibody test and a 4th generation, combination HIV antibody/HIV p24 antigen test ?

I'm really scare and concern the test method is not accurate enough and my 9 weeks negative result is not reliable. I cannot sleep well for these few weeks. Please help me

Thank you very much ! May God bless you all

1.  Yes, I already said that.

2. At 9 weeks the two types of tests give equivalent results.

Your fears are unwarranted.  EWH

Dear Doctor,

Only a standard HIV antibody test or a 4th generation, combination HIV antibody/HIV p24 antigen test will show the numerical results right ?

How about a 3th generation or 2nd generation ? I 'm really doubt the test method the hospital performed.

Thanks

Your fears are silly.  Other generations of tests would also give both numerical AND RELIABLE test results.  If you really want to know what the test was, you should ask the lab, not play these guessing games but either way, I am confident that your test results are reliable if they were done in an established laboratory.  EWH

Good news Doctor,

I just called the lab and they told me they used 4th generation test

Thanks for the support anyways
