The Evidence for HIV Self-Testing to Increase HIV Testing Rates and the Implementation Challenges that Remain

We describe the evidence regarding the impact of offering HIV self-testing (HIVST) and explore the gaps that need to be filled to design and implement HIVST programs.

Numerous randomized controlled trials found that offering HIVST increases HIV testing rates. However, these trials used an oral HIVST that was provided for free and there is no research examining the impact of offering blood-based (finger prick) kits or charging for HIVST kits. The trials also used various methods for distributing the HIVST kits, but there is little research comparing distribution methods. Study participants varied in the HIV testing method they chose when given choices, suggesting that offering multiple HIV testing options may be needed to maximize testing rates. Despite the consistent finding that offering HIVST increases HIV testing rates, questions remain that need to be answered in order to maximize the potential of this new biomedical technology.
