A range is going to include all the tests and how they may associate with each other !
For if one number changes, this also has an effect on the rest of the numbers !
It is a subject which many people have no idea about how it really is to be !
Doc Reams used to laugh behind the scenes, because people were always trying to zero in on the numbers and most never came to realize the simpleness of it all !
So, a person could not understand it, unless they properly understod some very Basic Facts, which most people never came to understand !
I only know of "one" man in the whole world who came to understand it more than everyone else, and he stopped doing the testing because unless a person could find Top Quality foods to eat, you could not Solve the problem completely !
So he went into the agricultural business of teaching people how to grow Top Quality foods, which people could then eat and this would Solve the Health problems without all the testing and problems associated with it !
The Simple part about all of this, may be that by raising Top Quality Foods to eat, this may Solve most all Health problems !
