4th Generation/DUO test

Male 83 - False negatives

 
Dear Sir/Madam
Is it possible Hiv combi test (elisa) to show a false negative result in case you have been infected many years ago? (The question is due to some comments found in the web, where some people state that some test did not recognize the virus since the infection took place many years ago etc - which i do not
understand)
 
Thanks

DNA PCR HIV

 
Is there any published data that show test accuracy and validity for the DNA PCR based on the number of days from exposure?  I tested on day 10 from a possible exposure and I would like to know if there is anything that shows accuracy of this test at day 10.
 
I realize I should do the antibodies test later to be most certain, but I am aslo wondering if maybe I should take the DNA PCR test again, now that I am on day 18 or should I trust the 10 day and just wait?  Would the 18 day be enough time from the 10 day to have any higher accuracy?
 
Thank you

Exposure Scare

 
Hi,
I am from India, I had protected sex with a lady of unknown status, way back
in October last year. The condom didn't fail, or break atleast as my
understanding was. It looked intact with a bubble like thing in the tip. The
lady also said after I finished that it was fine.
This was my first ever sex encounter and the last till date. I was somehow
not comfortable with what I did and since then I had a couple of tests done
for HIV, hepatitis and Syphilis.
The first HIV test I did was at the 10 weeks mark, a simple antibody for both
the strains, with some mothod called "ElectroChemiluminescence Immuno Assay."
It was negative.
The second I did at 12.5 weeks mark, this time for Hep and syphilis as well.
This time, the test done was a duo (or thats how I understood it, as it said
Ag+Ab). It was also negative with the results for hep and syphilis also
negative. The test for HIV this time stated "Chemiluminescence".
This was in the last week of Jan.
I have a few questions
1. How risky was my incident in the first place? Did it even warrant testing?
2. How conclusive are my results?
3. These tests are not ELISA, so what are these? EIA or ECLIA? I tested in
India. Are these methods and tests reliable at all. If so, are they as
reliable as ELISA?
4. I am healthy, have no diagnosied health probelsm till date. In this case,
can late sero conversion happen? (The reason for this is for the past 15
days, I have been suffering from extreme joint and muscle pains. I don't have
flu symptoms)
5. The duo test I have taken (If at all my belief that it is DUO is correct),
by any chance if Antibodies are not formed, should it mean that the Ag part
should have been picked up?
Thanks a lot for your time. Due to these body pains, I am very worried.
 

antiboty and antigen test

Hello,I had a HIV test, which looks for antiboty and antigen of HIV, after 92 days.The result was negative (0.37).However the people in the test center just told me that this test was perfomed by enzyme immunoassay method and definetely not ELISA.They also did not know the generation of the test.1)since the test looked for both antiboty and antigen of HIV was it certainly a 4th generation test?2)92 days are sufficient for an HIV test whatever the method perfomed was?thanks in advance

late detection

Male-83

 
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.
 
Questions:
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?
 
Thanks
