The same diseases are found in similar frequencies in HIV positive and
HIV negative intravenous drug users, and the overall mortality in the two
groups is the same.
The HIV antibody tests are not standardised. No gold standard has
been used and may not even exist to determine specificity. The tests are
also not reproducible. The proteins which are considered to be specific
to HIV may in fact represent normal cellular proteins. A positive test
may represent nothing more than cross-reactivity with the many non-HIV
antibodies present in AIDS patients and those at risk.
