<unk> itself is not normally a diagnosis sought in the emergency department (i.e. via A1C)
Hyperglycemia can be found on laboratory testing
Asymptomatic patients do not necessarily require additional testing
Symptomatic or potentially symptomatic patients require additional testing
Check CBC, BMP, and ketones (if sick, additionally see DKA workup)
UA is only necessary if you are ruling out urinary infection or do not have serum ketones available and are using it as a screening mechanism
Obtaining HbA1c prior to initiation of therapy helpful to establish a baseline
