Muscle testing for allergies?

has anybody on here ever muscle tested for any allergies. If you dont know what im taling about ill explain. You raise your arm straight out and hold somethong you fear you may be allergic to and resist with that arm as someone tries to push it down gently. If it goes down you are allergic. You can try it by saying your own name. You will be able to resist the push if you say a lie like, my names bill you wont be able to resist the push because thats not good for your body and your ming knows it.
