The effectiveness of PRANAN devices has been tested using MORA bioresonance technology. Developed by Dr. Franz Morell and engineer Enrich Rasche.

Bioresonance uses electromagnetic waves to keep the body in balance. Scientists Fritz Popp and Ross Adey have described these electromagnetic signals as a means of cellular communication.

This simple test compares the changes that occur in the body when it experiences electromagnetic radiation emitted by mobile phones during a call with calls received when a PRANAN protective device is placed in the mobile phone.
