It is currently accepted that a
positive Western blot (WB) HIV antibody test is synonymous with HIV
infection and the attendant risk of developing and dying from AIDS.
This test is done to confirm a positive screening
for HIV antibodies. To date, the only routinely used methods for
demonstrating the presence of HIV are the ELISA and WB antibody tests. Both
tests check the presence of antibodies i your blood to proteins of the
Virus. However whereas the HIV antibodies EIA tests is performed by
challenging the blood sample against a control which carries a mixture
of HIV proteins, the HIV antibodies Western Blot looks at several specific
proteins typical of the immunodeficiency virus.
