Abstract
A blood glucose measurement device, a blood glucose calculation method, and a blood glucose calculation program capable of accurately measuring a blood glucose level by using light are provided. The blood glucose measurement device includes a light sourcethat outputs measurement light Lto be input to a living body; a light detectorthat detects the measurement light Lpropagated inside the living bodyand generates a detection signal in accordance with an intensity of the measurement light L; and a computation unit that obtains a time lag between a temporal change in a first parameter related to an oxygenated hemoglobin concentration and a temporal change in a second parameter related to a deoxygenated hemoglobin concentration based on the detection signal, and obtains the data related to the blood glucose level based on the time lag.
