Method and the device which decide the glucose level which is in the midst of organism organizing have been based on the measurement and thermometry of the response for the electric field of organization. In order to improve accuracy, at least between, 0.2MHz and 100MHz three frequency ranges namely 1kHz and 200kHZ, combine, the range where it exceeds 1GHz should it understands, that, as for the reason response of organization in the frequency range where these differ is because it is controlled due to the fact that mechanism differs.< Selective figure >Figure 5生体組織中のグルコースレベルを決定する方法及び装置は組織の電界に対する応答の測定及び温度測定に基づいている。正確度を改良するため、少なくとも3つの周波数範囲、即ち1kHzと200kHZの間、0.2MHzと100MHzの間、1GHzを超える範囲が組み合わせられるべきであることが分かっており、その理由はこれらの異なる周波数範囲中の組織の応答は機構が異なることにより支配されるためである。【選択図】図5
