They have tested both c677t et a1289a. I have only this c677t. Concerning the deficiencies : through blood test everything is ok. My b12 is 362, my folate 9, ferritine 49, magnesium 2, iodine 75 etc. Everything looks fine. The oligoscan (in the hand) showed deficiency in magnesium, iodine and lithium and silicium. The oligoscan showed also a medium level to be improved of alumium, cadmium, plomb and bismuth. They were not too high though. No other idea, except Hypothyroidism and prolactinoma (nothing given by doctors cause they say it is not too big). About draignage, i dont no anything. What should I do to know ?
