In order to determine whether the patient is infected with AIDS, the patient should go to the hospital and have blood tests for AIDS antibodies, antigens, or HIV viral load, which will determine whether the patient is infected with AIDS. If the patient has been diagnosed with AIDS and wants to clarify the specific status through examination, he/she can check the blood routine, liver function, kidney function, chest and whole abdomen CT, and inflammation index, so as to determine whether the patient is infected with secondary infections or not, and he/she should also complete the examination of the CD4+T lymphocyte count in order to clarify the status of the patient’s immune function, and at the same time, according to the patient’s specific situation, he/she should choose the appropriate antiviral drugs for treatment. At the same time, appropriate antiviral drugs should be selected according to the patient’s specific situation to prevent the patient’s CD4+T lymphocyte count from decreasing and progressing to the AIDS stage.
