The Particulars: Since 2006, the CDC has recommended routine opt-out HIV testing for early identification of infected people. Data are limited on the impact of this recommendation.

Data Breakdown:  A survey of more than 50,000 patients between 2002 and 2010 found that HIV testing increased by 33% when comparing the pre- and post-recommendation periods. Testing rates were highest among the young, ethnic minorities, and the poor. Rates grew faster among African Americans than Caucasians and among those seeking care at a community health center than at a private clinic.

Take Home Pearl: HIV testing appears to have increased among the general population following the CDC’s 2006 recommendation for routine opt-out HIV testing.
