In Chandra L. Ford et. al.'s "Perceived Everyday Racism, Residential Segregation, and HIV Testing Among Patients at a Sexually Transmitted Disease Clinic," they assert that involving racism when determining who to test may be a useful tool due to the high population of HIV and STD positive African American people. This is presented in order to allow for the justification of this type of prejudice when using testing methods. This was a test in order to also determine whether or not certain people due to their race would be more apt to get tested. This was presented in a scientific fashion in order to allow for statistics to be presented to the public to achieve the most accurate information.
