Abstract: Disclosed are an apparatus and a method for measuring a blood glucose level. In the blood glucose level measurement apparatus and method, the apparatus coupled to a patch with a microneedle formed in at least one area and configured to calculate a blood glucose level of a body fluid extracted from a user may calculate the blood glucose level by analyzing a reflected light beam reflected from the patch with a microneedle formed in a second area and correct the calculated blood glucose level of the user by analyzing data obtained by measuring a reflected light beam from a first area from which the body fluid is not extracted so as to measure a precise blood glucose level with an error being reduced in consideration of environmental factors influencing measurement.
