FAQ INSTI HIV Self-test
How does the INSTI HIV work independently?
The HIV self-test uses a simple flow-through technology to detect HIV-1 and HIV-2 antibodies using blood from a finger. The HIV home test does not recognize the virus itself, but the antibodies. The test point is only visible if HIV antibodies are present. The INSTI HIV self-test is easy to perform and very accurate, but only works if you carefully read and follow the instructions. You can test positive with the INSTI® HIV self-test already 21-22 days after infection, but it can take up to 3 months to get a positive result. A negative result may not be accurate until 3 months after infection.
How do I know if my HIV self-test has been performed correctly?
The INSTI HIV self-test has a built-in checkpoint to show that the home test has been performed correctly and that you have added the right amount of blood from the fingertip. If the checkpoint is not displayed, your home test did not work. If only the checkpoint is visible, it means that your result is negative and that you probably do not have HIV. If two points are visible, your test result is positive. This means that you probably have HIV. Although the results of the INSTI HIV self-test are very accurate, you MUST confirm a positive result as soon as possible that has been confirmed by a physician to begin treatment immediately.
How fast can I get a result with the INSTI HIV self-test?
After you have completed the home HIV test, you can immediately read your result.
How accurate is the test?
Many research studies have shown that the HIV test is extremely accurate if it is performed correctly. The accuracy of medical HIV tests is determined by the sensitivity (that all actually positive individuals are tested positively) and the accuracy (that all actual negative persons are tested negative). The INSTI HIV self-test has a sensitivity of 99.8-100% and an accuracy of 99.5-99.8%.
What is the "Window period"? - When is HIV detectable in the blood with the INSTI self-test?
After exposure to the HIV virus, it can take 3 to 12 weeks (21-84 days) before the body of an infected person produces enough antibodies to be screened for an HIV self-test. This is called a window period. IgM is usually released about 3 weeks after infection. This is one of the antibodies that the INSTI HIV self-test must detect. An individual can be positively tested with the INSTI HIV test after 21-22 days after infection, but it can take up to 3 months for a positive result to be achieved. Approximately 97% of people will develop detectable antibodies during this period. A negative result may not be accurate until 3 months after infection. If someone is exposed to HIV and receives a negative test result during the period of the window, they must test again 3 months after possible HIV exposure.
What if the result is negative?
Continue your efforts to prevent exposure to HIV, such as having safe sex and other preventive methods. If you think you have run a risk in the past 3 months, repeat the test after 3 months.
If you live in a situation where you are at more risk, it is recommended to test every 3-12 months.
What if the result is positive?
Consult your doctor or nearest test facility for a comparison result. Keep in mind that each HIV self-test is only a screening test and not a definitive diagnosis.
What if your result is invalid or you are not sure whether you have applied the test correctly?
Visit your doctor or the nearest testing facility for further HIV tests.
When should you test yourself with the INSTI HIV self-test?
If you notice any of these symptoms (see FAQ on HIV and AIDS) and have come into contact with HIV, we recommend that you do an HIV self-test. We recommend that you test yourself if you are sexually active, have multiple sexual partners, use intravenous drugs, or have sex with someone who has HIV.
Testing is quick and easy and requires only a small amount of blood. You can also have HIV tests performed by your doctor or the government health organization. If you prefer to test yourself at home in a familiar environment without anyone else, order an INSTI HIV self-test. You can order the test on our website.
How often do you have to test yourself with the INSTI HIV self-test?
The Center for Disease Control and Prevention (CDC) of the United States recommends that everyone between the ages of 13 and 64 during regular health care be tested at least once for HIV. For people with specific risk factors, CDC recommends testing once a year. Anyone who participates in high-risk activities (for example, sharing needles to inject drugs, having sex with HIV-positive people without a condom) must perform an HIV self-test every 3 months. This frequency of testing would ensure that the infection is detected as quickly as possible.
The HIV test
There are different types of HIV testing. An HIV test measures whether there are antibodies against HIV in your blood, or whether the virus itself is present in your blood. In the standard HIV test a tube of blood is taken and tested in the laboratory. Depending on the test method, your blood is tested for the presence of antibodies (antibodies), HIV virus particles or both. The result is known within a week to 10 days. The advantage of the standard test is that it can show HIV in your blood after 6 weeks after infection.
In addition to the standard test, there is also an HIV rapid test. A drop of blood is sufficient for this. In the quick test you get the result as the name also says much faster: within an hour. Have you recently run the risk of HIV, then the quick test is less suitable.
