BIOSENSOR

摘要

A biosensor wherein BSA is added to a reagent layer containing an enzyme reacting specifically with glucose so as to electrochemically measure the concentration of glucose in the whole blood employed as a sample. When the response properties of the sensor are measured by using whole blood as a sample, the addition of BSA exhibits no effect on the response properties of the sensor at hematocrit levels ranging from 25 to 65%, while the effect of hematocrit on the response properties of the sensor is relieved depending on the amount of the BSA added at hematocrit levels of 25% or lower. Thus, the effects of hematocrit level and temperature can be reduced and a highly accurate measurement can be conducted.
