The high glutathione is a good thing, not a bad thing. You did say he is taking supplements which boost glutathione. The high glutathione might explain why there is no detectable mercury in his blood. As soon as the mercury gets to his blood, the glutathione helps rliminate it. It doesn't tell you how much mercury is in his organs though. I didn't see a number for aluminum. why is his iodine level so high? Does he eat plenty of seaweed or fish? Too much iodine or too little iodine can cause thyroid problems. Did they test for lead, cadmium, arsenic, and other heavy metals?

The high phosphorus is a concern. Does he drink carbonated beverages? If so, he should stop.
