4th Generation/DUO test


Hi Doctor 
The facts: 
-Test made on 07/05/2012. Name: HIV combi (elisa) (results was available after 24 hours). 
-I had protected sex (never broken condom) with about 12  sex workers when i was in the army (before 6 to 7 years and more). 
-About 2 months before the HIV test I had an MRI test.  
-At the time of the HIV test i was little cold with a little  cough/flu.
1) What is HIV combi (elisa) test, is it an approved test?
2)Should I rely on my HIV result NEGATIVE, is it conclusive or should I retake the same test or any new other HIV test? 
2) Does MRI, flu/cold affect the results?

HIV Testing

Hi, Close to 6 months ago, I had unprotected vaginal sex with a sex worker (Not sure in what state of mind I did that, but I did that...). Since then I got tested twice.
a 74th day test and a 88th day test.
The first test at 73 days says:
Detection of HIV I and II antibodies - Result : Non-reactive (.31)
The 2nd one at 87 days says:
HIV - 1+2 screening(Ag+Ab) : Non-Reactive
Method: chemiluminescence
Are these tests reliable? I am from India... and I did the first test in a diagnostic center and the 2nd one in a very large, reputed superspeciality hospital.
By any chance, is the 2nd test a 4th gen DUO? If it is, will that be reliable for Antigen testing that late?
Can my test results be considered conclusive?
I am suffering from knee joint pains and some other dicomfort like acne... So I am worried...
Thanks for your help

Should i still worry for an HIV infection?

i am a 33 year male and 42 days ago i had protected sex with a sex worker.Since i couldnt ejaculate, she took out my condom and she started mastrubating me.
1. Is it possible that with mastrubation you can be infected with HIV?What if her vaginal fluid were in my penis and with the mastrubation they enter into my urithra?she used also lubricant during the mastrubation.
2. Since then i have done one month after the intercourse a RNA PCR test which was negative, below 20 copies per ml, a rapid test and a Duo test 42 days after exposure, which were also negative.
Should i worry? do i need to repeat any other tests?

HIV ab/ag Index went up

Hi guys,
4 weeks ago, I've had sex with a girl and condom broke. I immediately pulled out and went to bathroom to wash my penis and hands.
I've had a PCR RNA HIV test as well as the Antibodies/p24 antigen test after
10 days and both came back negative.
I've repeated both tests again after 4 weeks and once again both came back negative.
However, I've noticed that the index for the ab/ag test went up after the 2nd test compared to the index of the 1st test. (0.15 after 10 days and 0.31 after 4 weeks).
Both indexes are way below 1 but would the higher latest index mean there is a  conversion in progress...?
2nd question : is PCR RNA testing after 4 weeks conclusive?
many thanks.

Acute Hiv-infection?

Hello, I had 5.5 weeks ago unprotected sex with a sex worker. I know that this was very stupid.
 2 weeks after the infection I had a sore throat. I have that now, after 5.5 weeks still, if a bit better. After 2.5 weeks I had then got even mild diarrhea occurred occasionally in 2 weeks again. The lymph nodes felt swollen at times. A doctor and no nurse but could not feel anything.
 After just over 3 weeks ago I went to the doctor. HIV antigen-antibody test was negative. Normal blood count.
 After 5 weeks, I got 4 strange pimple. They looked just like a little bubble and are now still little red hat is pick.
 Unfortunately, I totally scared. Are these signs of an acute Hiv-infection? How safe it was a test after 3 weeks?
