The usual blood tests do not usually detect HIV. Blood tests are mainly for routine blood tests, liver and kidney functions, and do not check for AIDS-related indicators. Only through blood tests for HIV antigen antibodies or HIV viral load can a patient be tested for HIV infection. These tests are relatively private and will not be performed at will. Therefore, the usual blood tests cannot detect HIV infection. If you want to find out if you are infected with HIV, you should go to a hospital and have your blood drawn to check for HIV-related indicators to determine if you are infected. Once the infection is confirmed, treatment with antiviral drugs should be given as soon as possible. At present, China will provide free antiviral drugs to AIDS patients, through antiviral treatment, can prevent patients from entering the AIDS stage.
