Early AIDS is usually not accompanied by other symptoms, so it is impossible to diagnose whether or not one has AIDS through symptoms. If patients want to know whether they are infected with AIDS, the accurate way is to take an HIV test. HIV tests often include HIV antibody tests and HIV nucleic acid tests, and AIDS can be detected through the following symptoms and tests, combined with high-risk groups: I. High-risk groups: If the patient has multiple sexual partners or sexual partners who are AIDS patients, has a long period of intimate contact with AIDS patients, or Children born to HIV-positive patients with syphilis, gonorrhea, non-gonococcal urethritis and other sexually transmitted diseases will have an increased likelihood of suffering from AIDS, and patients are advised to undergo regular HIV tests to confirm whether they are infected with the disease. HIV testing: 1. HIV antibody test: When a patient is infected with HIV, a large number of HIV antibodies may be produced in the human blood, and although HIV may not be completely eliminated, it is possible to confirm whether the patient has HIV infection by testing for HIV antibodies. Therefore, if the patient is positive for HIV antibodies, it usually means that the patient is infected with AIDS; 2. HIV nucleic acid test: HIV nucleic acid test is done by directly detecting the presence of HIV nucleic acid structure in the blood, if the test is positive, it may indicate that the patient has HIV in the blood, but the HIV test may be false positive, so it is recommended that the patient take several tests to confirm the infection Therefore, patients are advised to take several tests to confirm the infection. Clinical symptoms: Some patients may experience unexplained immune dysfunction, prolonged low-grade fever, or susceptibility to infection by pathogenic bacteria causing seborrheic dermatitis, oral ulcers, herpes zoster, etc. In addition, there may be symptoms such as generalized lymph node enlargement and lymphoma. If the above symptoms occur for unknown reasons, attention should be paid to the possibility of HIV infection.
