Introduction
Human immunodeficiency virus (HIV) antibodies are specific proteins produced by the immune system in response to infection with HIV. Their presence can serve as an important basis for detecting infection. If test results are abnormal, individuals should promptly visit a正规 hospital for further evaluation and confirmation. Human immunodeficiency virus is the virus that causes AIDS.

The human immunodeficiency virus is the virus that causes AIDS. After infection, it attacks the body's immune system. The immune system responds by producing these specific antibodies, but there is a "window period" during which antibodies may not yet be detectable even though the virus is already present; therefore, follow-up testing may be necessary.
Antibody testing is a common method for HIV screening. A positive result must be confirmed through confirmatory testing, while a negative result does not completely rule out infection. Interpretation should take into account exposure history and the window period.
Maintaining a healthy lifestyle is essential, including avoiding high-risk sexual behaviors, not sharing needles, and practicing good personal hygiene. In cases of potential exposure, timely post-exposure prophylaxis (PEP) should be initiated. Regular health check-ups and strengthening the immune system can help reduce the risk of infection.
