Description
Estimated cost for HIV Antibody Test at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The primary purpose of the HIV antibody test is to diagnose HIV infection. It is used for screening in at-risk populations, confirming suspected cases, monitoring the effectiveness of treatment, and as part of routine health check-ups. This test is also used in blood donation centers to ensure the safety of the blood supply.
Normal Range
A negative result indicates no HIV antibodies detected, which is the normal range. A positive result suggests the presence of HIV antibodies, indicating a possible HIV infection.
Low Values - Possible Causes
Low values, or a negative test, are expected in individuals without HIV. Common reasons include: absence of HIV infection, very early stage of infection (window period), and successful antiretroviral therapy leading to undetectable levels of the virus.
High Values - Possible Causes
High values, or a positive test, indicate the presence of HIV antibodies. Common reasons include: confirmed HIV infection, recent exposure to HIV, false positives due to other conditions (e.g., autoimmune diseases, recent vaccinations), and technical errors in testing.
