HIV confirmation testing is an important step in diagnosing HIV infection. The initial antibody-antigen screening test is not a definitive test for HIV infection, so confirmatory testing is required. In certain cases, the same specimen can be used to perform both the initial screening and HIV differentiation tests. In other situations, an additional sample is required.
p24 antigen neutralization assay
The p24 antigen neutralization assay is used to confirm the presence of HIV. The results of this test are reported as reactive or nonreactive, based on a pre-determined cutoff value. Samples are tested in duplicate to verify the results. If the initial test shows a positive result, the patient can be considered infected. This test also includes a negative component.
HIV RNA Test
The HIV RNA test for HIV confirmation testing detects HIV in most people within 1-4 weeks after infection. Some people may need to wait up to three weeks before they are able to detect HIV RNA. HIV testing should always be done as soon before possible HIV exposure.
ELISA Test
An ELISA test to confirm HIV infection uses a dye to detect HIV antibodies. The liquid changes colour if there are marker antibodies present. It remains clear if they are absent. A coloured specimen indicates that the person may have been infected. Clear samples indicate that the person is uninfected. The first two generations that use ELISA testing look for antibody only. The third and fourth generation test for antigens.
NAT test
The NAT test is used for HIV confirmation to monitor viral loads in chronically infected people. The test is a quantitative method that can detect viral load as low 20 copies/mL. This test is commonly used in clinical practice.
RT-PCR Test
The RT-PCR test for HIV confirmation is an enzyme immunoassay that detects HIV RNA. It requires the use of specialized techniques and operating environments to extract viral DNA. It is more sensitive, specific and reliable than other HIV tests.
Viral load tests
The routine HIV load test is performed by healthcare providers for HIV positive patients. It should be checked at least yearly, and more often if you are having any symptoms of HIV infection. Because it indicates if your blood levels are high or low, viral load is crucial. High viral loads can cause rapid loss of CD4 cells and HIV disease. Sometimes, however, the viral load does not change and should not be taken as a cause of concern.
