We aimed to investigate clinical practice in the offering of HIV tests
and subsequent uptake in a central London genitourinary medicine (GUM
) clinic. A random sample (n=330) of attenders at 3 inner-London GUM d
epartments was surveyed. Reasons for and rates of offering of HIV test
s were recorded and analysed in relation to demographic, risk group in
formation and uptake. The results were integrated with the latest unli
nked, anonymous seroprevalence data for the clinic. After exclusion of
patients known to be HIV-positive or to have recently undergone HIV t
esting, HIV tests were offered to 96% of homo/bisexual men, 55% of het
erosexual men and 60% of heterosexual women. Comparison with anonymous
HIV seroprevalence data showed an inverse relationship between seropr
evalence rates for heterosexual men/women (2.5% vs 1%) and rates of HI
V test offering. A lack of research into the policy offering HIV tests
may have resulted in inconsistencies in practice. An evidence based p
olicy should offer HIV tests in line with seroprevalence.
