Lessons learnt from the first Australian 'pop-up' HIV testing site.

Lessons learnt from the first 'pop-up' HIV testing site in Australia suggest that highly visible testing activity was acceptable in the context of inner Sydney and that pop-up sites may be a useful adjunct to clinic-based models. Further evaluation of alternative testing models is needed to inform the scale up of HIV testing in Australia.

A novel time-limited pop-up HIV testing service for gay men in Sydney, Australia, attracts high-risk men.

Unlabelled: Background HIV diagnoses have been increasing steadily in Australia and are concentrated among gay, bisexual and other men who have sex with men (GBM). HIV testing is a key control strategy, and in 2013, a novel time-limited pop-up community HIV testing service (Pop-up) was introduced to raise awareness and increase testing options for GBM. The Pop-up service offered rapid HIV tests only.

A novel assay detecting recall response to Mycobacterium tuberculosis: Comparison with existing assays.

A strategy to reduce the burden of active TB is isoniazid preventive therapy for latent TB infection (LTBI). However, current assays used to diagnose LTBI all have limitations. In these proof of concept studies, we compared the agreement of a novel flow cytometry assay detecting CD25/CD134 co-expression with QuantiFERON-TB Gold In-Tube (QFN-GIT) and Tuberculin skin test (TST) in the detection of recall immune response to TB.
