If you know what you are infected with this works well. I think you can also go to the suspected frequency, use a positive offset to get the zapper effect, while using the most effective frequency for a specific pathogen. I'm not sure if it will work as well on the suspected pathogen though?
Also frequencies don't go through cells and lymph until they reach over 1 Mz? So you can't get all of the pathogens in one zap session. A carrier frequency over 1 Mz might solve this problem?
