Very Urgent: Pam Sing Branched Chain Reaction HIV1

Hi
I have a sexual encounter last year Julyb11 2014 with CSW and after that i have so many symptoms of HIV like swollen LN and mouth infection and idid fourth generation Elisa 2-3 times that comes negative but i still considering i am HIV positive because of my symptoms thats not go away. So by request my doctor order a HIV 1 RNA ( Branched chain DNA) for that i have some doubts
1. I have time with last sexual encounter more the 15 months is this test is effective now because window period now is more then 15 month
2. He mention only for HIV 1 that means if i have HIV 2 this test is not useful
3 Is there is same test available in toronto for HIV-2 also
4 This test is called PCR or that is different one.
5. This test is good for all strains of HIV
6. What are the chances for coming false negative of positive for this test
7. If any other virus is present in my body other hen HIV then this test can come positive or its specific for hiv
8. Is there is any other test which is other then antizen or antibody and useful for hiv1&2
9 Do you have any information how many people in Canada have HIV1 infected and how many are of HIV2 as i have doubt that in my case i have any rare strain of HIV because so far my antibody test come negative.
10. Is in toronto pcr for HIV1 and HIV2 is possible.
please reply i have to go for lab quickly thanks

HIV possibility?

I had anal(gay) sex with a guy 7 days ago, we had protected anal sex and unprotected oral sex. I am so concerned as I had two mouth ulcers on my lips, I gave him oral for around 15 second.
What is my risk of contracting hiv?? Please help.

PCR window

I did a PCR DNA test at 23 days post-exposure. I understand the window period for testing is 7-21 days. As I had done it later, does this increase the chance of a false negative?

Query ? Doubts ?

Question:
Had exposure - in May
Symptoms flu kinda post 2-3 weeks
Sore throat more than 40 days
Still Improper stools

So many tests

Tested at 28th, 42nd, 56th, 89th, 93rd, 102nd and 122 days

One hiv 1 pcr rna qualitative - not detected 103nd day

I had my Id Nat test ( nucleic acid test ) on 124th day
It came not detected for HIV 1/2 / hepatitis b / hepatitis c !

Followed by one HIV duo test At 119 the day ! ! Not detected !

I have Defieciency in vitamin d and b12 as I am vegetarian

Any more testing needed ?

Id Nat ( screening test )( Roche cobas t scrn mpc )

It's highly sensitive and specific authorised by government of India !

1) Can i consider conclusive?
2) Can all be false negative?
3)If there is no antibodies formed due to compromised immune system then antigens or rna or Dan should be detected ? can all be false negative??
4) I know 4 conditions delay the window period for 6 months but that s for antibodies ? In mean time antigens / rna Dna should be detected ?

Last follow up ! Query concern ?

PCR test at 10 days post exposure

Hi there,
I am a BC resident and went to a clinic today and the Dr. Ordered a PCR hiv test. After reading more I'm not sure if it was the NAAT one or not. Going on assumption it was not. I had a one time possible exposure with a male of unknown status (I'm female) 10 days ago and since then I have been worried sick. We did not use a condom and he half ejaculated inside me, half on my stomach.
If the doctor ordered a regular PCR test, and I went today (10 days post exposure) ... is that too early? I now see I should've waited 14 days and again this has now raised my anxiety. I already have the paper to retest at 3 months but that seems like an eternity away.
Thank you

Rna/4th generation/rapid test

Hello doc

I had a sex with a Cuban csw with a condom. I did not check to see if it had a hole, tear, or broken. after a week I came down with a high fever, sore throat, and well affected tonsils. I became alarmed and took the following test.

week 2 (antibody test)
week 5 (4th gen test)
Week 7 (4th gen/rna)
Week 10 (blood rapid test)
Week 13 (blood rapid test)

First question is what are the chances that the rna test was a false negative because I might be an elite controller? and have not develop antibodies, although I heard these cases are ab positive.

Second can I have some type of super virus that might of gone undetected such as crfs?

Third Does the 6 months compete window period only apply when testing alone for antibodies?

Fourth most ID specialist in my area test for one year. is this because some people might go undetected for so long or just because extreme conservatism?

Thank god bless

Is it conclusive?

I had unprotected intercourse in December. I did a 4 generation HIV and 8 panel std and early test, all negative at 5 months. At 7 months I had another PCR RNA done by my dr. and was also negative, I don't need to worry anymore? I had Hep A when I was young. Would that delay seroconversion? Thank you for all your help.

Possible HIV exposure??

Dear Dr. Please help.

I recently had a condom break situation. I had safe sex with a pilot at night and while passing my stool I saw some drops of blood (I realized the sex was rough but safe)by next day everything was fine, no more blood or anything similar.

I met another guy who is a flight attendant and during sex the condom broke, i didn't realize until I disengaged myself from his penis (I was the receptive partner) . He hadn't come..when he threw the condom away I went to cross check if everything was fine but the condom was broken (I assume it broke three minutes ago when i was sitting on him, previously I checked the shaft had condom on) and ever since then have been living a nightmare... I asked him if he was negative and he said he was but I do not trust him as he tried to enter unsafe the first time..
I do have herpes though the first and last outbreak was in february 2015 on my lips. i had syphilis in past which i do not have anymore after I took penicillin shots. All my VDRL tests (4 in last 9 months) have come negative

It's been three days now and waiting until 6 weeks seems like waiting for a decade. I have read 100's of hiv forums to asses risk ..

Please if you can provide a risk assessment and if there's any test that I can go through before 6 weeks. I am hiv negative as of june 2015.

Additional info: The tip of condom must be broken..I am not sure if it broke during sex or while the guy was taking the condom out
I live in India where the treatment of positive people is appolic. You can't get a job because every organization puts you through mandatory health checkup..You can't date anyone because the extremely few Gay men who are out would run miles away from a positive person...I know nothing can be done of what has happened...please help me with assessment.
