HIV Testa

HIV Test

Acquired immune deficiency syndrome (AIDS) is a disease that lessens the efficiency of the immune system progressively. The infection of HIV happens by the transfer of semen, blood, vaginal fluid, breast milk, or pre-ejaculate. However there are some HIV tests that help you to recognize the symptoms of AIDS. HIV testing is done to identify antibodies against HIV that specify infection with the virus. HIV tests are given below for your information.

The information regarding HIV test is given below

ELISA Test

HIV testing can be carried out on any of three body fluids i.e. salvia or urine, blood. The blood test is a series of two tests. The first test is called ELISA test (enzyme-linked immunosorbent assay) is exercised to display a large number blood samples for the existence of HIV antibodies. The second test is performed for confirming the result whether it is positive or negative. If the results of this test are negative it means the blood samples do not contain HIV. On the other hand if the blood samples contains HIV antibodies it shows the positive results (reactive). Sometime the ELISA test could be reactive though the blood samples do not contain HIV antibodies. It is called as false positive. That is why the initial results of this test is not accepted as true positive. The Elisa test usually repeated if the initial result of this test found positive.

The Western Blot Test

The Western Blot Test is the most regular and confirmatory test utilized for this intention. Some laboratories verify ELISA positive results with others tests rather than Western Blot test.The other tests like the radio-immunoprecipitative assay (RIPA) and immunofluorescence assay (IFA) are also done. These tests are as correct as Western Blot test. The false positive result’s rate of these tests is extremely low after the confirmatory testing. So a positive result of ELISA test that is established by Western Blot test and IFA test means the present blood sample includes HIV antibodies. It means the person has been infected with HIV.
