HIV less than 1 is negative, which generally means that you are not infected with HIV. The test method used is the enzyme immunoassay, and the normal value is 0 to 1.00, with a value greater than 1 being positive. So your current figure of 0:01 is negative, which means that you are not infected with HIV. It should be noted that after HIV enters the human body, the body in the production of HIV antibodies during this period, generally lasts 2 to 4 weeks, this time can not detect the full amount of antibodies, only through the nucleic acid detection of the virus to determine the presence of HIV infection The current anti-immunodeficiency virus antibody is a quantitative test method, the accuracy of this test method is higher than the qualitative test method, if the infection through the window period after the test is 0.01 is what you call a negative-positive test results. If the test result is 0.01 after the infection has passed the window period, then the test result is negative and positive. It is recommended to ask the infectious diseases department to give professional answers to the problems involving human immunodeficiency virus tests in time to avoid delaying the condition.
