This article provides an overview of HIV testing in France in 2009, with a specific focus on the anonymous and free testing program. In 2009, five million HIV serology tests were performed, of which 8% (approximately 400,000) were conducted at an Anonymous and Free Testing Clinic (CDAG). The number of serology tests performed has remained stable since 2006, both overall and within the anonymous testing system. Of these tests, approximately 10,900 were confirmed positive, of which 12% (approximately 1,350) were performed at CDAGs. After a downward trend since 2005, the overall number of positive tests tended to increase between 2008 and 2009. Positive test results from CDAGs followed a similar trend. Compared to the overall screening system, CDAGs are unique in that they screen a younger and higher-risk population. The regional analysis shows the same disparities as in previous years; Île-de-France and the overseas departments remain the regions with the highest screening rates, but also the highest number of positive serology results. Comparing these data with those from mandatory HIV reporting reveals a link between testing activity and early diagnosis. With a view toward shifting strategy toward increased testing outreach, these data provide a baseline measure of HIV testing activity in France. (R.A.)
