HbA_1c testing and time in range outcome

HbA1c testing	Time in range outcome
Evaluates single HbA1c levels	Evaluates continuous glucose levels
Compares HbA1c levels 3 months apart	May compare fluctuations for any given amount of time
Does not capture hypoglycemic or hyperglycemic levels occurring in the same day	Captures all glucose levels for the given time frame and identifies time within a safe range
Less likely to capture impact of acute interventions	Likely to capture impact of acute interventions
