One of the biggest mistakes my doctor found(have had him for over 10 years he is good, listens to me and does not mind trying silver and CG(Colloidal Gold))is that tests results that show normal they don't take all the tests done over the years and really look at them! What might be normal for you is not for me! So if all the tests are in the "normal" range, that does not mean it is normal? You and your doctor have to look over all your tests! See what is normal for you. My doc say quite a few of his patients(no names of course) had their issues fixed or at least under control, just because the test showed normal but was not. The labs don't really say much if all is in normal range!
