FIELD: medicine. SUBSTANCE: method involves measuring mean temperature of body areas by recording infrared radiation emitted by body surface in the region of sternum and back of hand or foot. Relative thermographic coefficient (RTC) is calculated as RTC =t/T, where t is the mean temperature of back of right or left extremity hand or foot area, T is the mean temperature of sternum area. RTC value being less than 0.94, the patient is to be included into the group distinguished by blood circulation disorders in the extremities. Otherwise, the patient is judged to belong to healthy person group. EFFECT: high reliability of diagnosis.
