The clinical microbiology laboratory has a mandate to provide reliable, accurate
susceptibility data in a time frame that is useful to the clinicians requesting the information
to optimize clinical outcomes and, when possible, to reduce the emergence
of resistance.
This mandate is served by selective reporting of results to the ordering
clinician from isolates obtained from individual patients and by providing collective
data on local prevalence of resistance to be used for empiric therapy.

문장이 좀 긴데요. mandate를 어떻게 해석해야 할 지 몰라서 해석이 쉽지 않네요
문장이 너무 길다면 mandate만 어떻게 해석하는지 알려주시면 감사하겠습니다.
