HIV-2 Window Period


I had one unprotected vaginal sexual exposure with a girl. Next day after exposure, we went to a clinic to test. I knew my results won't be accurate but I just wanted to know her HIV status. Clinicians used Alere Determine HIV1/2 Ag/Ab test and she was negative. I also tested with Alere after 50 days and with 4th generation lab test after 60 days. Both were negative.

What I'm worried is, she said she had relationships with African people nearly 2-3 years ago. I know that some African people has HIV-2 type of virus, different than HIV-1. I wonder if she was HIV-2 positive, does this means a prolonged window period? Basically, does HIV-2 has different window period than HIV-1? I searched some articles but I couldn't find exact reports. Alere Determine doesn't have any HIV-2 spesific antigen detection so there needs to be established HIV-2 infection to detect antibodies. But I do not know what is the maximum window period to establish HIV-2 antibodies. I'd be so glad If you can help me.

Thank you!

HIV Test at 2 months & 1 Week Negative

Thanks for taking the time to look at this question.

I honestly have a fear of HIV, I'm honestly scared that I'll get it and its always on my mind. I'm gay and I recently broke up with my ex partner over 2 months ago. The last time we had sex was about 9 weeks ago, and yes we didn't wear protection. I found out that he had raw sex with someone else while we were together in the last two weeks that we were together. Fortunately we know that person he had sex with and they both say they are negative and my ex is now on prep.

But I am still paranoid as I have chronic fatigue and most of the symptoms are similar to HIV and its playing on my mind and affecting me every day.

I had a little over a month check and it was negative, I just had a 9 week test and this was also negative. What are the chances say one of them did have HIV that my 9 week negative result could still come up positive at the 12 week mark? I can't keep going on like this :(

Oral sex and deep kissing

Hello, Thanks for this awesome service.

I have a quick question regarding my exposure yesterday (the day before this question is being sent).
I met with a guy who said he is married and disease free. we decided to hang out at my place, we had long session of deep kissing and mild lip biting and he ended with giving me a blow job. but today i found out from him that he didn't get tested over a year. So this bothers me a lot now. i didn't notice any bleeding or sores. i didn't had any sores that i remember. but i always thought kissing was safe sex activity until i see some discrepancies now. this case is m4m

please advice if i need to get tested, and when should i get tested. i was going to get tested after 28 days with a blood draw. do you think it will be accurate by that time. thx

4th generation hiv test

46 days after the risk I did a test that said the following:
Anti hiv 1 + 2 and negative p24 antigen
Method: Electro-chemiluminescence
This test is based on the simultaneous determination of IgG anti-HIV1 and anti-HIV2 and antigenaemia p24, which allows to reduce the delay between contamination and virus detection.
According to what you have mentioned before, the test that combines the search for antibodies and antigens at the same time is of 4 generation and the window period is 6 weeks in 99% according to many experts. The question I have is that in my test it says: Anti HIV 1 + 2 AND ANTIGEN P24 NEGATIVE
Method: Electro-Chemiluminescence and after says: This test is based on the simultaneous determination of IgG anti-HIV1 and anti-HIV2 and antigenaemia p24, which allows to reduce the delay between contamination and virus detection. I have read that those of 4 generation usually look for igG and igM and p24 antigen. Could it be that my test only looks for IgG and p24 antigen or have IgM ignored or is it normal? Is it still 4 generation to look for antibodies and antigens? Can I stay calm for being 4? Thank you very much for your help andgreetings from barcelona, you do a magnificent job

test vih 4 generation

Good morning,
I did an HIV test 45 days of the risk situation but did not say if it was 4 generation or what generation it was the following:

Method: Electro-Chemiluminescence

This test is based on the simultaneous determination of IgG anti-HIV1 and anti-HIV2 and antigenaemia p24, which allows to reduce the delay between contamination and virus detection.

Is it a fourth generation test? The Spanish health ministry told me that a 4-generation test passed 6 weeks of the risk situation.
Thank you.

Please I Beg for a kind reply (Anxiety at the top)

Dear Sir/Madam
this is my 3rd time positing to you but no reply at all. I am totally broken due to fear and anxiety of hiv please help me to sort out this.
I must admit that after an unprotected brief anal intercourse a second foolish mistake to do a test alere determine at home while i was not totally aware of the procedure. I did and a grey control line and a faint grey line appear after few minutes on the test strip i was shocked and assumed that my life has been ended up. after reading much articles and who website i came to know that this might be an invalid test as what i saw was a shadow and alere determine requires coloured line for reactive as many other experienced the same and WHO also stated in their practice module 9. since then i repeated test as follows

High top antibody rapid home test (non reactive at 7.5 week)
Alere determine done by me at 8.5 and 9 week non reactive

Since i know i should confirm my result i went to a health care provider in my area and tested with SD Bioline hiv 3.0 test non reactive at 10 week.

I tested again by myself at 13 week using alere determine hiv 1/2 nonreactive
at 15 week i went to a local community health care centre where they tested me with hiv antibody test rapid test non reactive
at 20 week i went to the same health care centre for the retest and they test me with alere hiv combo twice and reassure me that i am free from hiv.

Please help me to sort out my anxiety. i shall be thankfull
