FIELD: medicine.
SUBSTANCE: method for non-invasive control of a blood metabolite level involving using a sensor array to measure electromagnetic impedances in the patient's epidermic layer and in one of the layers including the patient's skin layer or subcutaneous layer more than once, until an impedance difference exceeds a threshold; calculating the impedance reflecting the above difference with the use of an analogous circuit and an individual adjustment factor specific for the patient's physiological characteristics; and measuring the patient's blood metabolite level on the basis of the impedance and a measurement algorithm of blood metabolite levels, which provides comparing the measured blood metabolite level to the respective patient's electromagnetic impedance. What is also presented is a system controlling a level of at least one of the substances: glucose, electrolyte or a target substance.
EFFECT: invention enables avoiding excessive experiments to adapt it easily for controlling the patient's blood metabolite level.
