HIV infection is an viral infection caused by the human immunodeficiency virus (HIV) that gradually destroys the immune system, resulting in infections that are hard for the body to fight . WHAT IS HIV WINDOW PERIOD
The window period is the time it takes for your body to produce HIV antibodies after you have been infected by the virus. In most people, this period is between 2 and 12 weeks. In a very small number of people, the process takes up to 6 months. During the window period, you might be infected with HIV yet the test may show HIV-negative. Here's how that can happen. Let's say you have unprotected sex on Saturday night and become infected with HIV. On Monday, you get an HIV test. The test almost certainly will come back negative, because your body has not yet had a chance to make antibodies, which are what the HIV test is looking for.
Even if you go for an HIV test 1 or 2 months later, your results might be negative because your body still has not produced antibodies. It may take 3 months after exposure for the test results to be 97% accurate, and 6 months to be absolutely certain. If you think you have been exposed to HIV and your test results are negative, be sure to get retested in 3 to 6 months- just to be sure.
It is very important to note that if a person is infected with HIV, they can still transmit the virus to others during the window period. There are a number of tests that are used to find out whether a person is infected with HIV, the virus that causes AIDS. These include the HIV antibody test, P24 antigen test and PCR test. HIV antibody test. Following are the commonly used lab based tests: Antigen test (P24 test); Fourth generation tests or; PCR test.Below here is the list of some other tests like:
Home sampling: It is generally recommended that the HIV test is done in a health care setting. However, in some countries "home sampling" kits are available. With a home sampling kit, a person can take a sample (usually a blood sample) and then sent it off to a laboratory for testing. A few days later, the person phones up a special number, gives their individual identification code, and is then given the result over the phone. If the result is positive a professional health specialist will provide emotional support for the person.
For "home sampling", the major advantages are convenience, speed privacy and anonymity. In countries where HIV tests are not free, home sampling may be a cost-effective way to get tested. But for some people the lack of face-to face counselling before and after the test may be a disadvantage.
Home testing: A home self-test involves a person conducting a rapid antibody HIV test in their home. The person takes either a blood or saliva sample and can interpret the result within minutes. A positive result will require a further confirmatory blood-test in a clinic. Using an HIV test kit at home means that the results are learned on the spot without any counselling. This type of testing is not generally recommended because of the lack of emotional support for the person, and a positive result must be confirmed by further testing at a clinic. At present, this kind of test cannot be legally sold in many countries.

Even if you test HIV-, that doesn't mean you should feel like you can have unsafe sex.
The diagnosis of HIV is a two-step process. The initial screening tests, including ELISA and the rapid tests, are highly sensitive and can detect very low concentrations of anti-HIV antibodies. However, these tests are less specific and can lead to false positive results. Thus, a positive screening test should always be validated with a confirmatory test. According to the CDC, ELISA combined with a confirmatory test such as the Western blot or immunoflorocent assay test is 99 percent accurate.
- A Western blot assay – The western blot (sometimes called the protein immunoblot) is a widely used analytical technique used to detect specific proteins in the given sample of tissue homogenate or extract. It uses gel electrophoresis to separate native or denatured proteins by the length of the polypeptide (denaturing conditions) or by the 3-D structure of the protein (native/ non-denaturing conditions). The proteins are then transferred to a membrane (typically nitrocellulose or PVDF, where they are probed (detected) using antibodies specific to the target protein.
- An indirect immunofluorescence assay – A laboratory test used to detect antibodies in serum or other body fluid. The specific antibodies are labeled with a compound that makes them glow an apple-green color when observed microscopically under ultraviolet light.
- A line immunoassay - Commonly used in Europe. Reduces the chance of sample contamination and is as accurate as the Western Blot.
- A second ELISA – In resource-poor settings with relatively high prevalence, a second ELISA test may be used to confirm a diagnosis. The second test will usually be a different commercial brand and will use a different method of detection to the first. When two tests are combined, the chance of getting an inaccurate result is less than 0.1%.
