FIELD: medicine, namely surgery. SUBSTANCE: boundaries of biological tissue pathologic state are determined by measuring of capillary blood flow of skin or mucous membranes by means of apparatus "Laser analyzer of rate of surface capillary blood flow". First readings of sensor of laser Doppler flowmeter are recorded for undamaged section of skin or mucous membrane. Then sensor is positioned on section of body close to pathologic area and having capillary blood flow indications most approximate to normal ones. With sensor moved towards pathologically changed tissue, dopplerogram data are recorded. If readings of root-mean-square parameter of microcirculation change by 0.3 relative to undamaged section parameter, and asymmetry coefficient changes by 0.03, boundary of pathologic state of tissue is determined. EFFECT: enhanced truth and safety. 1 ex, 1 tbl
