How to diagnose allergies most efficiently and affordably, aside from muscle testing? have not had luck w allergist or osteopath. still have reactions

Depends: If a B/C allergist couldn't help you, then your problem may not be from allergies at all since there are other entities which mimic allergic reactions. Muscle test is a waste of time since it has nothing to do with any allergic reactions as we know them. Give a more detailed description on your symptoms so that we can understand what your needs may be.
