<p><strong>Background</strong>: While routine HIV testing in the general population is a national recommendation, actual practice may vary.</p><p><strong>Purpose</strong>: To determine risk factors associated with HIV testing after the adoption of a New York State law in 2010 mandating that healthcare providers offer HIV testing in all clinical settings.</p><p><strong>Methods.</strong>: Survey data from Monroe County, New York, were collected in 2012 for adults aged 18-64 years and analyzed in 2014. Logistic regression was used to identify risk factors independently associated with HIV testing and high-risk behavior.</p><p><strong>Results</strong>: Among adults aged 18-34 years, fewer Whites were offered HIV testing in the past year by their doctors compared with Blacks (34% vs 64%) despite having similar rates of any HIV high-risk behavior (20% overall). For adults aged 35-64 years, fewer Whites than Blacks were ever tested for HIV (42% vs 71%), offered HIV testing in past year (17% vs 40%), and reported any HIV high-risk behavior (3% vs 13%). Latinos showed intermediate levels. With logistic regression analysis, ever tested for HIV was independently associated with only race/ethnicity; offered HIV testing in the past year was associated with females, Blacks and Latinos, aged 18-34 years, and having a routine health checkup in past year; any HIV high-risk behavior was associated with only younger age. </p><p><strong>Conclusions</strong>: To improve HIV testing rates as well as compliance with state laws and national guidelines, targeted efforts should be considered that improve perceptions of risk and emphasize the value of routine HIV screening, including those directed at white adults and their health care providers. <em>Ethn Dis.</em> 2016;26(1):91-98; doi:10.18865/ed.26.1.91</p>
