4th Generation Antigen - Antibodies
What is it?
This is the latest generation test (HIV I/II Virus ELISA) for detecting infection from the human immunodeficiency virus HIV type I/II. It simultaneously detects the virus itself (p24 region) as well as the antibodies developed by the body against HIV type I and II.
Where Used
The test is valid if a sample is taken at least 4 weeks after the time of possible contact – infection (window period). During this time, both the copies of the virus and the amount of antibodies against the virus have reached detectable levels (approximately 99% reliability).
The test is used mainly for preventive and diagnostic purposes.
As a preventive test, it is used for:
- Early diagnosis of HIV infection, for immediate effective pharmaceutical intervention
- Between sexual partners to avoid transmission from a non-infected carrier
- Educating younger individuals to be vigilant against seemingly healthy carriers
- Prenatal and pre-surgical screening for timely implementation of appropriate measures
As a diagnostic test for HIV infection, attention is needed in the following cases:
- Possible positive result: To avoid false-positive results, confirmation with HIV PCR molecular biology test is required.
- Negative result: If the sample was taken close to the window period, repetition of the test with the same method may be needed after some time.
- Negative result: If there are very strong indications of HIV infection, confirmation with HIV PCR molecular biology test is required.
Reference Values -Normal Laboratory :
In non-immunocompromised adults, a negative result is typically valid against both positive and negative control sera.

The ELISA (Enzyme-Linked Immunosorbent Assay) test for the human immunodeficiency virus (HIV) has been established as an effective tool for screening and diagnosing the virus. This test detects antibodies produced by the patient’s immune system against the HIV virus. This process does not require much time and is relatively cost-effective, making it suitable for mass screenings at the population level or for evaluating HIV on an individual basis.
The ELISA test process begins with collecting a blood sample from the patient. The sample is then spread onto a plate coated with a substance (antigen) that recognizes HIV antibodies. If the antibodies in the sample react with this substance, a signal is generated that can be measured. The presence of this signal indicates the presence of HIV antibodies in the sample, suggesting a possible infection.
The ELISA test does not directly report the presence of the virus but only the immune system’s reaction to it. Therefore, if the result is positive, further tests such as the Western blot are required to confirm the presence of the virus.
The ELISA test for HIV has been widely used in many parts of the world as a primary means for preventing, diagnosing, and managing HIV infection. Regular testing and HIV screening are important factors in preventing the transmission of the virus and managing the infection in its early stages.
