If you have had 5 HIV tests that have been negative, it is extremely unlikely that you have HIV that was transmitted two years ago. If your question is can you be infected 2 years earlier and it be negative on tests each time for two years, the answer is virtually impossible. The reason for this is that the oraquick test has a 99.6% sensitivity and 100% specificity, meaning that the people who did not have the virus would test negative 100% of the time and that out of 1000 people who were infected, 996 people would test positive. This means that 4 people out of 1000 would test negative while still being infected - meaning 0.04% chance that if you had HIV, you would test negative. Now, if you this take this test twice, your chances go from 0.04% to 0.04%x0.04%=0.0016% chance, meaning out of 1,000 people, less than 2 people will have HIV but test negative. Take the test 1 more time, and now your chances are 0.000064%, meaning less than 1 person in 1000. The test is good for detecting virus infections that are greater than 3 months. So to answer your question, it is very very very unlikely that after 2 Oraquick and 3 other HIV tests that were negative, you would have HIV (unless you had a new exposure since that time.
I am attaching a link from the cdc for more information about the oraquick HIV test for your information: http://www.cdc.gov/hiv/resources/qa/oraqck.htm
As far as dormacy for the virus - it is certainly possible for a person to be asymptomatic from HIV for months, years, to even decades, meaning that they might not experience any symptoms and their white blood cell count can remain in the normal range for a long time, in some cases indefinitely. They can remain infected with HIV but maintain undetectable viral loads (while still their HIV test would be positive). This is not the same as a dormant herpes virus, however, that can hide virion particles in the nerve ganglia and not cause clinical infection. They are similar in the fact that the patient is not symptomatic, but the mechanisms are different and the word dormant is not frequently used to describe latent HIV infection.
I hope this is helpful. Please let me know if I can answer any further questions.
I am suggesting the second of the two in terms of "dormant" (which again is not a word that I would use to describe HIV infection): that someone can have HIV and the tests still pick it up but your body just hasn't become sick from it. If you were infected more than 3 months ago, it would be picked up already 99.999999% assuredly (based on the numbers I cited above).
I hope this is helpful. Please let me know if I can clarify any more information.
Certainly it is a scary diagnosis and if you are worried that you might have been exposed recently, it is valid - however if you are concerned about an exposure 2 years ago and have had 5 negative tests, you no longer need to be worried or creating 'what ifs' because it is virtually impossible that you are infected from that time.
That is actually very low risk - it is believed that the saliva has properties that actually inhibit the HIV, so you really must be safe after the low risk exposures and 5 tests.
It's my pleasure and have a good night. Happy birthday too!
Wow, congratulations! Is today your birthday? I just meant that its the Aquarius birthday season. What a lovely birthday present. Best of luck!
Well that is great news and I wish you a lot of luck with the pregnancy. Hopefully the anxiety will subside since this particular issue should not be a worry.
Best of luck!
You can refer to DrS in the question and then people will tend to differ the question to the person to whom it was posed. I'm happy to answer any questions that you may have. Again, best of luck!
i presume that dr S is offline... if you allow me i will answer your qeustion...
i agree with doctor S and i would say that the tests for HIV can still pick it up...
even though your friend is also partially right in saying that HIV can hide in cells such as some of the white blood cells (macrophages) in our body.. but not all the cells hide in the cells and that cannot prevent the HIV from not being detected from the most advanced tests such as PCR (polymerase chain reaction)...
nowadays the newer PCR machines have the ability to detect even a single copy of HIV RNA in a mL of blood...
so i find no way that they could have missed the virus in your body if they tested your properly...
what i can tell you is that it is all in your head.... you are being hypochondriac (i apologize for using these terms... this is not to hurt your feelings)
if you really really want to be DEAD sure that you do not have HIV then i would recommend that you get a PCR test done if you have not had that already...
one thing that i would like to add is that you have had ELISA four times and this test is nearly 100 percent sensitive for the detection of the virus (by sensitive i mean that if the test is negative you do not have the disease)..
the body will still produce antibodies to be detected unless you are severly immunocompromised.. which you are not... i am sure...
As Dr. Zia mentioned, the virus does not hide in your cells without the test detecting it, so after the numerous confirmations, you truly do not need to worry. As I mentioned above, the virus is NOT like the herpesvirus that can hide in nerve cells.
