Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to physics and can be used to determine functional state of a biological object. In the method of determining state of a biological object by recording and comparing gas-discharge luminescence structures around a standard object and the analysed biological object in an electromagnetic field created by an electromagnetic pulse generator, wherein the recorded gas-discharge luminescence structures around the standard object and the analysed biological object are converted to a digital code, quantitative parametres of these luminescence structures which reflect their characteristics are determined, corresponding points in space of the said parametres are determined for the standard object and analysed biological object, and from the distance between these points, deviation of quantitative parametres, characterising the state of the analysed biological object, from quantitative parametres characterising the standard object is determined. The novelty is that, the standard object used is made from non-biological material, gas-discharge luminescence structures around the standard object are repeatedly recorded, relative deviation δ is calculated in line with measured quantitative parametres of the gas-discharge luminescence structures around the standard object from their mean value and if δ≤10%, the gas-discharge luminescence structures around the standard and analysed biological objects are compared, and if δ>10%, output voltage of the electromagnetic pulse generator is reduced and/or stability of these pulses is increased until δ≤10%. A metallic standard object can be used. A standard object in form of a vessel with electrically conducting liquid can be used. In the proposed device for determining state of a biological object, which includes an electromagnetic pulse generator, sheet glass on the lower surface of which there is an electrode in form of a layer of electrically conducting optically transparent material, lens, optoelectronic digital converter, computer, information presentation unit, switching device which is made with possibility of successive connection of the generator with the standard object or the analysed biological object, wherein the first output of the generator is connected to the switching device and the second output to an electrode, the output of the lens is optically connected to the optical input of the optoelectronic digital converter, and the first output of the computer is connected to the output of the information presentation unit, the novelty lies in that, the device further includes a unit for calculating relative deviation δ in line with the measured quantitative parametres of gas-discharge luminescence structures around the standard object from their mean value and a logic decision unit, wherein the input of the said unit for calculating relative deviation δ is connected to the first output of the optoelectronic digital converter, the second output of which is connected to the to the first input of the computer, the second input of which is connected to the first output of the logic decision unit, the second output of which is connected to the input of the generator. The switching device can be made in form of an electronic or electromechanical switch. 
     EFFECT: increased accuracy of determining state of a biological object.
