HIV confirmation testing is an essential step in the process of diagnosing an HIV infection. HIV confirmation testing is required after the initial antibody/antigen screening test. It is not an indicator of HIV infection. 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 for HIV testing. Based on a predetermined cutoff, the results of this test can be reported as either reactive or non-reactive. The results are verified by having two samples tested. If the initial test shows a positive result, the patient can be considered infected. The test can also have a negative component.
HIV RNA testing
HIV RNA testing is used for confirmation testing. The HIV RNA test detects HIV in most individuals within 1-4 weeks of infection. It may take up three weeks for HIV RNA to be detected in some individuals. HIV testing should be done as soon possible after HIV exposure.
ELISA test
An ELISA test to confirm HIV infection uses a dye to detect HIV antibodies. The liquid changes in colour when the marker antibodies are present. When they are absent, the liquid remains clear. A colored sample means the person has an infection. A clear sample, however, indicates that they are not. The first two generations on the ELISA test only look for the antibody, while the third generation and fourth look for both antigens.
NAT test
The NAT test allows for HIV confirmation. It is used to monitor viral loads of chronically infected persons. It is a quantitative test that can detect HIV levels as low at 20 copies/mL. This test is widely used in clinical practices.
RT-PCR test
The RTPCR Test for HIV Confirmation is an enzyme immunoassay used to detect HIV RNA. It requires specialist operating environments and techniques in order to extract viralRNA. It is a more sensitive and specific test than other HIV tests.
Viral load test
The viral load test is a routine test performed by health care providers for people who are HIV positive. It should be checked at least yearly, and more often if you are having any symptoms of HIV infection. It is vital to know your viral load. This tells you if there are high levels or low levels of the virus in blood. HIV disease is more common in those with high viral loads. They tend to lose CD4 cells quicker and have a higher rate of death. But, it is possible for the viral load to fluctuate and not be a concern.

What are the four Health Systems?
Healthcare is a complex network that includes hospitals, clinics and pharmaceutical companies as well as insurance providers, government agencies, public officials and other organizations.
The ultimate goal of the project was to create an infographic that would help people to better understand the US health system.
Here are some key points.
-
Healthcare spending is $2 trillion annually, representing 17% of the GDP. This is nearly twice the amount of the entire defense spending budget.
-
Medical inflation reached 6.6% for 2015, more than any other category.
-
Americans spend 9% on average for their health expenses.
-
As of 2014, there were over 300 million uninsured Americans.
-
Although the Affordable Health Care Act (ACA), has been approved by Congress, it hasn't yet been fully implemented. There are still many gaps in coverage.
-
A majority of Americans believe that there should be continued improvement to the ACA.
