f-scan therapy

My f-scan therapist just called me and kind of ordered me to go back to her, because the old frequencies wont work anymore she thinks. I´m still not sure about the f-scan, if it´s really working or not, and have just ordered a new terminator since I can´t find my old one in the apartment..so braindead. Do you guys think the f-scan is a good machine for diagnosis of infections? I tried muscle testing on myself but not sure if I´m doing right yet. I get strange results.
