What subject is tested for HIV

HIV testing can usually be done in infectious disease, dermatology, or infectious disease departments. AIDS is a chronic infectious disease caused by human immunodeficiency virus, which is mainly transmitted through sexual contact, blood and mother to child transmission. If there are symptoms such as unexplained fever, lymph node enlargement, weight loss, etc., it is recommended to seek medical attention for examination in a timely manner. There are many reasons that may lead to the need for HIV testing, including high-risk sexual behavior, needle sharing, occupational exposure, risk of mother to child transmission, and unexplained recurrent infections.

1. Infection Department:

Infection Department is the main department for diagnosis and treatment of AIDS. The infectious disease doctor will inquire in detail about the epidemiological history, including whether there is a history of unsafe sexual behavior, blood transfusion, or intravenous drug use. If there is suspicion of infection, doctors usually prescribe a human immunodeficiency virus antibody test as a preliminary screening. If the result is positive, further confirmatory tests will be conducted. The Infection Department is also responsible for the antiviral treatment and long-term follow-up management of AIDS. Common drugs include tenofovir tablets, lamivudine tablets, efviren tablets, etc., but the specific medication plan needs to be formulated by the doctor according to the patient's situation.

2. Dermatology and venereology department:

Dermatology and venereology department also often receives AIDS related examinations. Many AIDS patients will have skin and mucosa manifestations at the initial stage of infection or during the course of disease, such as herpes zoster, oral candidiasis, seborrheic dermatitis, etc. When patients seek medical advice due to these skin problems, doctors may recommend AIDS screening. Dermatologists can also prescribe human immunodeficiency virus antibody testing and provide targeted treatment for related skin and sexually transmitted diseases, such as using acyclovir tablets to treat herpes and clotrimazole suppositories to treat candidal infections.

3. Infectious Diseases Department:

The functions of Infectious Diseases Department and Infectious Diseases Department overlap, and they are also core departments for diagnosis and treatment of AIDS. In some hospitals, the Infectious Diseases Department is directly responsible for the diagnosis, treatment and prevention of AIDS. The doctors in this department will assess the patient's immune status and determine the progression of the disease by testing CD4+T lymphocyte count and viral load. The Infectious Diseases Department will also deal with AIDS related opportunistic infections, such as Pneumocystis pneumonia, tuberculosis, etc., and guide patients to carry out standard antiviral treatment, commonly used drugs such as zidovudine capsules, nevirapine tablets, etc.

4. Centers for Disease Control and Prevention or designated hospitals:

Centers for Disease Control and Prevention or designated AIDS treatment hospitals in some regions have special counseling and testing clinics. These institutions usually provide free AIDS counseling and preliminary screening testing, and the testing process is strictly confidential. If the initial screening is positive, it will be referred to a designated hospital for confirmation and subsequent treatment. For individuals with high-risk behaviors but no symptoms, going to the CDC for anonymous testing is a common option, and the test results usually need to wait for 1-2 weeks.

5. Emergency department or fever clinic:

If acute symptoms occur, such as persistent high fever, severe sore throat, systemic rash, etc., and there is a recent history of high-risk exposure, you can go to the emergency department or fever clinic first. Doctors will make preliminary judgments based on clinical manifestations and arrange relevant examinations, including blood routine, human immunodeficiency virus antibody testing, etc. The emergency department can quickly handle acute symptoms, but diagnosis and subsequent treatment still require referral to the infectious disease department or infectious disease department. Acute symptoms usually appear 2-4 weeks after infection and can self resolve after 1-3 weeks. Regardless of which department is chosen, the core of HIV testing is to conduct human immunodeficiency virus antibody or nucleic acid testing. It is recommended that high-risk individuals undergo testing after the window period (usually 2-6 weeks). In daily life, unsafe sexual behavior should be avoided, and items such as toothbrushes and razors that may be contaminated with blood should not be shared. If diagnosed, it is necessary to actively cooperate with doctors for antiviral treatment, undergo regular check ups, maintain a good mentality and balanced nutrition, which can help delay the progression of the disease.
