The HIV test strips sold publicly are approved by the state and have undergone strict safety checks and are safe. However, the results of the test strips cannot be relied upon to diagnose or rule out HIV, and it is recommended that people with a history of high-risk exposure to HIV go to a regular hospital to have their blood tested.
HIV test strips are a new and quick way to initially screen for HIV, with an accuracy rate of about 95% to 98% when used correctly. HIV test strips are strictly controlled by the State Food and Drug Administration before they are sold to the public, making them a safe way of self-testing.
HIV test strips are generally used six weeks after high-risk HIV behavior, i.e., after the window period, when most infected people are able to develop antibodies in their blood that can be detected. However, due to individual differences in the length of the window period, the test results of the test strips may be inaccurate and therefore cannot be used as a basis for ruling out or confirming the diagnosis of AIDS. Therefore, if you have a history of high-risk exposure to HIV, you need to go to the hospital and have your blood tested in order to make a definitive diagnosis.
