A positive HIV antibody test is usually the result of a blood test, which means that a person is positive for HIV antibodies. When a person is infected with HIV, a large amount of HIV antibodies can be produced in the bloodstream. A positive result from a blood test indicates that a person is likely to be infected with HIV. However, this HIV antibody test has a certain false positive rate, which means that a positive result does not mean that a person is 100% sure to be infected with HIV, and further confirmation tests must be done. If the confirmation test is negative, it means that the person is not infected, and the test is positive for HIV, so don’t worry too much at the beginning.
