Tridot test accuracy after 6 months


But there is a scenario when a negative HIV test may not be all that it appears. When testing for HIV, there is a short window period when a person can test negative and actually have the virus in his or her system. And the reasons are simple: when HIV infection occurs, a person's immune system begins to develop specialized proteins called antibodieswhich are specific to the individual pathogen it aims to neutralize in this case HIV.

It is those antibodies that most antibody-based HIV tests detect. It takes some time for enough of those antibodies to be produced for an HIV test to detect them. Therefore, if too little HIV antibody has been produced when a person gets tested, the test result will be returned as negative despite the fact that an actual infection has occurred.

Some types of HIV tests will only look for antibodies. Most physicians will recommend repeat testing three months after exposure to ensure one has a truly negative HIV test result. Some doctors will also recommend another HIV test six months after.

These are more capable of detecting HIV during the early, acute stages of infection, shortening the window period by as much as a month. These tests work by detecting the HIV-specific proteins called antigens, which initiate the immune response and are therefore produced more rapidly after infection than antibodies.

If all of the tests are negative, and a person has had no new HIV exposures, then they are considered to be HIV negative and clear of infection. However, if a person has another possible exposure to the virus between tests such as condomless sex or shared injected drug usethe tests will need to be repeated, starting over from the point of the new exposure. Always speak with your healthcare provider about when you need to be tested and if retesting may be needed to provide greater confidence in the results.

With all this being said, rapid HIV tests are still commonly used in clinics and at home, and they test for HIV antibodies. Available in most retail drug stores, OraQuick detects HIV antibodies in saliva with results in 20 to 40 minutes. But unlike similar tests are given at clinics and hospital, the in-home version will produce approximately one false negative result out of every 12 tests performed.

If the test is performed incorrectly or too soon, the likelihood of a false result will only be greater. If using an in-home test, don't take any chances.

Having learned that there are many different types of tests, let us go into the details of how to test for HIV.

The chances of having a false negative result therefore depend on the rate of new HIV infections incidence in a community. In a low incidence setting, with very little ongoing transmission of HIV, most of the HIV infections which tests need to pick up will be infections that people have had for several months or years. For these long-standing infections, tests are extremely accurate and false negatives are therefore extremely rare.

However, in a community with a higher HIV incidence and ongoing transmission of HIV, a higher proportion of the HIV infections which tests need to pick up will be recent infections that people have only had for a few weeks. For these, tests are less reliable and false negatives may occur. False negatives have also been reported in people taking antiretroviral medicines, whether as HIV treatment, pre-exposure prophylaxis PrEP or post-exposure prophylaxis PEP.

The accuracy of a single HIV test depends in part on characteristics known as sensitivity and specificity. Sensitivity is an indication of test performance when testing people who do have HIV, whereas specificity reflects test performance in relation to people who do not have HIV.

To some extent, the chances of having a false negative result also depend on how common HIV is in your community. When very few people among those testing actually have HIV, it is even more likely that a negative HIV test result is accurate. In HIV testing, the period of time after infection and before seroconversion during which markers of infection are still absent or too scarce to be detectable.
