HIV testing is necessary to detect whether a person is infected with HIV or not. It tracks the movements of the HIV antibodies and if it finds it, it returns a positive result. It is known to offer an outstanding and accurate diagnosis for many years now.
Techniques used to test for HIV
Let me share some of the most widely used HIV testing methods around the world today.
First, we have the HIV test known as ELISA, a procedure that is the most preferred and most patronized among them. It needs a patient’s blood sample which will be analyzed for signs of HIV antibodies. It is performed along with a confirmatory operation known as the Western Blot. In the event that the Western Blot test is unable to identify the existence of the antibodies, specialists can undertake another confirmatory method known as the Radioimmunoprecipitation Assay. It utilizes a fully-functioning diagnostic instrument that will search for the antibodies not noticed by the Western Blot test. It will cost the individual more and require a much longer time to supply results. Only professional lab technicians may execute the test.
There is also an HIV testing option called the Rapid Latex Agglutination Assay. It is a substitute that is not as tricky and costly as the other HIV testing techniques. It is recommended for developing countries that are searching for an effective HIV screening technique that is affordable.
Last but not the least, there are also home HIV screening tests intended for those which value their privacy. The utilization of home screening tests was presented some years back. In this situation, a patient is requested to send over to the laboratory a sample of his or her saliva. Even though the process is less tiresome, they say that saliva is not an exceptionally efficient specimen to pick up the HIV antibodies. They still think that blood samples are way much better for this role.
Prevention is better than cure when it comes to HIV
Many medical experts say that it is still better to defend against the assault of HIV to your body than to get affected with it and find ways to remedy it. HIV tests and treatment may cost so much, and there is no guarantee that you will be fully cured. Never forget to make use of protection when having sexual relations so as not to pass on the infection to other people.
