Method of orientation screening diagnostics of functional disturbances in human body is carried out using hardware-software system bioplasm nls health analyzer and lies in location of possible area of pathological process and its intensity (reliability 79.7%). Method of screening diagnostics is based on noninvasive use of electromagnetic signals (1,8 – 8,2 Hz) and biological feedback (BF) among operator, patient and hardware unit.

As a result an outline of BF is formed, initiating trigger receives a reaction of patient’s brain waves to an irritant and sends digital signal back to hardware unit. This technology allows saving time of research, including mass prophylactic examination, helps to determine personal program of precise diagnostics necessary for specification and verification of prior diagnosis, helps to estimate a dynamics of functional changes in human body.
