There are several methods for checking whether a person is HIV positive or not. They can provide accurate information about the severity of the disease in an individual, and tell how the HIV antibodies are reacting to the virus. Some of them utilize modern equipment and tools that boast of the latest technology, while the others lean more toward the unconventional ways.
HIV screening tests and diagnostic procedures are for the purpose of monitoring the activities of the HIV antibodies in the human body of a patient. They have been proven to provide successful and precise diagnosis for several years now. However, there will be times when the traditional ways will show insufficiency, thus the help of the least popular methods are tapped.
The following are just a few of the standard HIV diagnostics medical professionals still use up to now:
ELISA is a method that is the most widely accepted and most patronized among them. It requires a patient’s blood sample which will be tested for traces of HIV antibodies. It is conducted alongside a confirmatory procedure named the Western Blot. Both these methods require state-of-the-art technology and are much more expensive than the others.
If the Western Blot test fails to detect the presence of the antibodies, scientists can try another confirmatory procedure called the Radioimmuniprecipitation Assay. It uses a sophisticated diagnostic tool that will look for the antibodies missed by the Western Blot test. It will, however, cost the patient more and take a much longer time to provide results. Only expert lab technicians are allowed to conduct the test.
For those that are on a tight budget, the Rapid Latex Agglutination Assay is an alternative that is not as complicated and expensive as the previous methods. It is suitable for developing countries that are in need of an efficient HIV screening technique minus the sky-high costs.
There are also home HIV screening tests available for those that value their privacy. In the United Kingdom, the use of home screening tests was introduced six years ago. In this case, a patient is asked to send over to the laboratory a sample of his or her saliva. While the process is less tedious, they say that saliva is not a very reliable specimen to detect the HIV antibodies. They still believe that blood samples are way better for this job.
It is really expensive to undergo all these tests. This is the reason why it is better to prevent the attack of HIV to your body than to get infected with it and look for ways to cure it. Always remember to use protection when having sex, and just try to live a kind of lifestyle that will not put you at risk of these kinds of diseases.
