Title: Testing and Linkage to HIV Care in China: A Clustered Randomized Trial
Brief Summary: This study will evaluate the effects of a comprehensive approach (One4All) to increase the percentage of patients that receive their HIV testing results and counseling.

Primary Hypothesis: The One4All approach will increase the proportion of individuals who have completed all tests to confirm HIV diagnosis and received counseling within 30 days of screening HIV+, given they have screened HIV+ on the initial test, from 40% to 60%.
