First and foremost: Clarify any medical questions and concerns, particularly about an important diagnostic result, with you physician and other medical professionals. Don't rely on any website for medical information or advice.
"False positive" is a statistical idea used to assess how accurate a test is. If a test give a "false positives" then it reports positive when in fact the material being tested for is NOT there. The opposite is a "false negative" when the test does not detect the material of interest when it is actually present. The best test have low rates of both fales positives and false negatives.
This is a way of assessing the inevitable imperfections of various screens and tests. So, when you first receive the screening results, your medical professional would never say "I got your screen, and it says here that it is a false positive". If the lab processing your screen knows that it's a false positive when they process it, they wouldn't report it as a positive. But more important, they could never know that your result is a false positive. All they can know is that according to procedures, and with everything properly done, the result on this particular screen came out 'positive'.
A result is exposed as a false positive only when adequate and competent followup is completed, and this followup tells you that the true result is negative. So if your medical professionals have concluded after adequate followup that a result is a false positive, it means that you do not have whatever was tested for.
On several sites I ran across this list of dozens of factors known to cause false positive HIV antibody test results: http://www.tig.org.za/pdf-files/affidavit-aug06/54%20Factors%20known%20to%20cause%20false%20positives.pdf
False positives are very rare when being tested for HIV. However, there are occasions when a test result may be returned positive intially only to get a negative confirmatory result.
HIV testing is a complex process. Most HIV tests are not looking for the HIV virus, but anitbodies produced by a person after they are infected with HIV. These antibodies may resemble other antibodies produced in response to other infections (Syphilis).
Also, there may have been an issue when transporting texting kits, or perhaps the manufacturer of the kits needs to be notified that a particular lot # of tests isn't working correctly.
Cases of false-positive test results do happen, but they are very infrequent. Over 99% of the time, HIV tests are accurate the first time.
Your body begins to produce anti-HIV antibodies once it find out it has been infected.
So yes, it does.
if your partner is clean and the only needle used is for insulin which is a clean needle every time can you get hiv from this? and also what is a false positive for blood work for hiv
if its positive you do have the virus
Only if the first HIV test was false positive can the test results change.
Yes, in general the standard STD test battery includes a test for HIV infection. However, a person may not test positive immediately after infection with HIV, which is why they are generally counseled to get a second HIV test in six months.
HIV tests are highly accurate, especially if taken more than once. With one testing, there are generally 15 false positives out of 1000. With a second test, the chance of a false positive is 1 in 250,000.

The HIV medication Atripla causes false positive THC urinalysis tests.
It is possible to have a false negative HIV test, particuarly early in infection with HIV. If a partner has a true negative HIV test, it's not possible to get HIV from them.
To be exposed to does not always mean that you will be infected. If contracting the disease you will still not test positive until some time afterwards.
It means that the test was positive for HIV.
Maybe, but even if Atripla showed up on a drug test, as long as there is a valid medical reason to take it (HIV infection), then there should be no problem. This is not a drug used for recreational purposes.
It would be almost impossible to test negative if a person is HIV positive.
No. The CDC will not contact you. Your doctor will inform you if you test positive for HIV.
No; you would not be HIV positive.
