Hi there.. I am concerned about my 11 year old son.. He had a blood test during a routine yearly physical (because he is a high level competive swimmer and had been have lots of problems with muscle recovery and feeling run down etc.) the physio looking after his shoulder injury recommended. It turned out his levels of b12 very extremely high.. White blood cells on the low and urea was low as well as several other things.
