A study was undertaken of the views of users of two genitourinary medicine (GUM) clinics in England on unlinked anonymous testing (UAT) for HIV. The UAT programme measures the prevalence of HIV in the population, including undiagnosed prevalence, by testing residual blood (from samples taken for clinical purposes) which is anonymised and irreversibly unlinked from the source. 424 clinic users completed an anonymous questionnaire about their knowledge of, and attitudes towards, UAT. Only 1/7 (14%) were aware that blood left over from clinical testing may be tested anonymously for HIV. A large majority (89%) said they would agree to their blood being tested, although 74% wanted the opportunity to consent. These findings indicate broad support for UAT of blood in a group of patients whose samples are included in the HIV surveillance programme. The findings suggest the need for greater attention to be given to the provision of information and, if replicated in a larger survey, may justify a reappraisal of UK policy on UAT.
