I find it difficult to trawl through the forum to find a simple list of diagnosis and treatment list for Mast Cells disorders. So I have made my own. Please correct any mistakes I’ve done Diagnosis: check list of symptoms: CFS is a mast cell disorder. http://forums.phoenixrising.me/index.php?threads/me-cfs-is-a-mast-cell-disorder-hypothesis.18437/ Skin biopsy Serum Tryptase blood test Bone Marrow biopsy for presence of mast cells and to test tryptase 24 Hour N-Methylhistamine Urine test Allergy tests Source: http://www.mastocytosis.ca/diagnosis.htm There is also the thread "Four M.E/CFS Tests almost no one has ever done." http://forums.phoenixrising.me/index.php?threads/the-four-me-cfs-tests-almost-no-one-has-ever-done.19624/ Are these Four ME/CFS tests also related to Mast cell disorders???? Treatments http://www.mastocytosis.ca/treatment.htm Is the www.mastocytosis.ca link I've used accurate? If anyone knows anything, please correct any mistakes so that I can figure out if this can help me or not. It will be great to have a simple summary for those of us who don't know if it relates to them.
