I joined this forum tying to get as much info as possible on mast cell disease. My son has never been diagnosed with mast cell, but he has had 2 anaphalctic episodes One in 2003 and 2007 it was at that time that we started monitoring hgis tryptase levels. Since Jan. of 2007 they have been between 15-16. In June of 2010 it was 18.9 and December of 2010 20.3..He has no symptoms of any kind and never has. He does seem to have the high tryptase and it appears to be on the way up again...so now I it is a waiting game again to see when he has the next attack. I spoke with Dr. Akin sometime ago regarding Nick and he asked me about several syptoms Nick could be having and I told him he has none of those. Dr. Akin gave me his info and email and told me I could get ahold of him if something changes, but has since changed hospitals. Does anyone have Dr. Akin's email at Brigham Young. I would be so thankful.
