IgE Food Allergy Test: Immunoglobulin E (IgE) are antibodies produced by the immune system. When you’re allergic to a food, IgE triggers the release of chemicals in certain cells, which manifests as an allergic reaction. These food allergy reactions occur within minutes of eating a food and symptoms range between minor to severe. It’s estimated that 15 million Americans suffer from food allergies.
IgG Food Allergy Test: Immunoglobulin G (IgG) is the most abundant antibody, comprising of 73 percent of all circulating antibodies. IgG food allergy tests identify delayed food allergy reactions. These reactions can worsen overtime. IgG reactions are more difficult to notice since they can occur hours or even days from the time the food was eaten. This is why doing a good food allergy test is extremely beneficial.
If you are considering an IgG test please also consider adding the IgE test to it as well. We have seen both of these providing clients with the answers they need. The IgG and IgE test kits can be done in the SAME test kit with the SAME blood draw!
