This document summarizes the initial experience with the first HIV self-testing kit available in the UK. Over 27,000 kits have been sold since April 2015. Most buyers are male and located outside major cities. About half of buyers had never tested for HIV before. User feedback indicates the test is easy to use and results are easy to read. A small number of false positive and invalid tests were reported. While self-testing is proving popular, more data is still needed on access to care for reactive results and the impact on testing rates and behavior.
