Bioresonance diagnostics is an energy-information system that enables detection of changes in the body by measuring the frequency of wave characteristics in it. Every material system has an optional interaction with electromagnetic radiation of a specific wavelength; its quantum energy corresponds to the energy for breaking down connections (entropic potential) of the main system components. Nonlinear analysis system (NLS) of diagnostics with special bio-indicators measures the energy resistance of the human body cells without exceptions, as well as the activity of bacteria, parasites and other infectious agents on the cells. The software processes and analyses obtained information comparing them with the best parameters already contained in the database. The base contains ten thousand spectral etalons of various cellular processes to be compared with in order to get the results.
