Abstract: The present disclosure relates to a method for transmitting and receiving non-received biometric information, and more specifically, to a method for transmitting and receiving biometric information, wherein, when there is biometric information that a communication terminal has not received from a sensor transmitter, the reception of the non-received biometric information is controlled differently by determining, from received adjacent biometric information, whether the domain to which the non-received biometric information belongs is a dangerous domain or a normal domain.

Abstract: The present disclosure relates to a method for transmitting/receiving biometric information in a continuous glucose monitoring system, and more specifically, to a method for transmitting/receiving biometric information, in which, in each communication cycle, first, an identifier of the last transmit packet received by a communication terminal is transmitted to a sensor transmitter, and the sensor transmitter transmits, to the communication terminal, a transmit packet generated after the last transmit packet, and thus biometric information generated by the sensor transmitter may be transmitted without loss to the communication terminal.
