HIV testing is now available anonymously and confidentially. There are many places where you can get an HIV test and there are several ways to get a result. A "confidential" test involves giving your name and medical history. The results will go into your medical records, and you can discuss them with your doctor and insurance company. However, if your test is positive, it will be reported to the local health department and will be used to determine the rate of HIV infection in your area. The privacy laws do not prevent the test from being disclosed, but they can help you know what to expect when you get the results. The most common HIV tests work by detecting the antibodies that a person produces to fight off the disease.
Usually, the human immune system produces antibodies within 28 days of infection. However, it may be up to a year before a person begins to display symptoms. Furthermore, during this time, they may still be transmitting HIV to others. For instance, a person who is infected with HIV can pass it on to their sexual partner, drug-sharing partner, and even to a nursing infant. The CDC has estimated that about 2.5 million HIV tests were administered nationwide in both public and private settings. These tests are available at health departments, freestanding counseling and testing centers, and even doctor's offices. Additionally, mobile testing units are also available for public use. In an indirect immunoassay, a sample of blood is loaded with an antibody against the virus.
This antibody binds to the anti-HIV antigens in the sample. This process then produces a color change that inversely corresponds to the HIV antibody concentration. The test results are then reported as optical density/cut-off (OD/CO).While you should not be alarmed by a negative test, it is crucial to make sure your doctor contacts you immediately if he or she suspects that you have the virus. The reason for this is that HIV tests can produce false-negative results. A negative test can be indicative of recent exposure and may result from a virus that has not had time to develop antibodies to it.
Currently, the CDC recommends getting a HIV test for people between the ages of thirteen and 64. Individuals who are at higher risk of infection should have more frequent tests. This includes those who have multiple partners, do not use condoms, or inject drugs with shared needles. Knowing your status will help you take better care of yourself and prevent further complications. You will also be able to get the necessary medical treatment. After an HIV test, you should take anti-HIV therapy, which can reduce your virus levels and prevent AIDS. If you are positive, it is crucial to follow all precautions to prevent the spread of infection. Discuss the possible risks with your sexual partners and use condoms with every sexual encounter. You should also avoid sharing any injection equipment with others.
