Abstract

Methods and apparatuses for blood glucose measurement are provided. A first glucose concentration in a body fluid of a user is detected based on a first measurement interval. A first blood glucose level of the user is determined based on the first glucose concentration. A glucose concentration measurement interval is changed from the first measurement interval to a second measurement interval according to an occurrence of an event. A second glucose concentration in the body fluid is detected based on the second measurement interval. A second blood glucose level of the user is determined based on the second glucose concentration.
