The early tests all required the body to develop antibodies before being able to test HIV positive. Newer tests can be done based on HIV particles.
You must be tested to know for sure.
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.
Only if the first HIV test was false positive can the test results change.
The major concern with HIV testing that is inaccurate is when people test too early. In order for an HIV test to be accurate, there have to be enough antibodies present for the test to pick up. If a person tests too soon after infection, the body may not have had time to develop antibodies which can be measured. In these cases, a test will return a negative result, when in fact the person is HIV positive.
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.
As soon as they test positive for the HIV virus.
It is possible. HIV testing is a delicate process because a person may be infected with the virus but not test positive until several months after infection. Example: A person is exposed to HIV and waits two months, then gets a routine HIV test. Because the individual is in their "window period" (the amount of time it takes for someone to develop enough HIV antibodies to test positive) they may have a negative test result despite having been infected. HIV test sensitivity varies. When getting tested for HIV, it is important to know the sensitivity of the test being used because follow-up testing may be required to provide a conclusive result.
Nothing but the test results…
There is a huge difference between them. HIV Positive means that the test found HIV-Antibodies in your blood (you can find them in the mouth sometimes). A HIV-Negative test means that the solution did not find any signs of HIV in your body and your in great shape.
Indeterminant means that an HIV test is neither positive nor negative. Typically, if an HIV test is indeterminant, another test will be performed to confirm the results.
