What is the meaning of not detected HIV test result?

A "not detected" HIV test result means that the test did not find any detectable levels of HIV in your blood or saliva sample. This typically indicates that you do not have HIV, or that you are in the very early stages of infection when the amount of virus in your body is too low to be detected.

It's important to note that a "not detected" result does not necessarily mean that you are definitely HIV-negative. There is a possibility of a "false negative" result, where the test fails to detect HIV even though you may have the infection. This can occur if you test too soon after potential exposure to the virus, during the "window period" when your body has not yet produced enough antibodies or antigens for the test to detect.

To ensure an accurate diagnosis, it is recommended to follow up with repeat testing after the recommended window period, which can vary based on the specific test used. If you have concerns about your HIV test result or have risk factors for HIV, it's important to consult with a healthcare professional for guidance and further evaluation.
