Re: Re: Divergent HIV strains and antibody tests

In his rapid response "Divergent HIV strains and antibody tests" (14th October 2003), Christopher Noble gave 6 tests in answer to our question regarding the antibody tests that include HIV-1 group O specific antigens. Would he please tell us:
(i) in which countries these tests are routinely used?
(ii) Are they use as screening tests or as confirmatory tests?
