An allergy is a hypersensitivity to an environmental antigen (allergen). If a person has a hypersensitivity to an antigen they will have a patholigic (disease) response when exposed to that antigen. When the hypersensitive individual is initially exposed to the antigen, they will produce allergen specific antibodies, primarily immunoglobulin E (IgE), that will during subsequent exposures bond with membrane proteins on the mast cell membrane. This bonding allows degranulation (the release of stored chemicals) of the mast cell. Mast cells manufacture and store chemicals, including histamine, that are responsible for the affects of inflamation.

Hello, Richard. I ca?
Hello, Richard. I can't say what your children's bloodwork showed and whether it led to the "high histamine" diagnosis. But I can tell you that we don't typically test for histamine itself during allergy testing (either skin tests or blood tests)-what may be tested for are IgE antibodies against certain foods. Histamine is a chemical substance that is released by mast cells in the body (these are part of the immune system) and that is sometimes found in certain foods. Histamine is a substance that leads to many of the symptoms of allergies. I suspect that the nutritionist was not basing her assessment of 'high histamine' on bloodwork but rather simply on the fact that your kids have allergies, since food allergies are in part mediated by histamine release in the blood. Therefore, she is likely recommending to avoid foods that stimulate release of this substance or themselves contain it.
