Health regions

Individuals who receive an HIV diagnostic test are assigned to a geographic region based on their residence or, if unknown, the address of the ordering provider. About 27% of tests are missing information on address of residence and assigned based on provider address.
Health regions are aggregations of public health units and their boundaries (see Tables and Figure below).
