When people think of allergies what typically comes to mind is the standard allergy symptoms we all know or have experienced. Our bodies may mistakenly identify a substance as toxic and produce antibodies against common foods or environmental substances. This type of reaction is caused by IgE antibodies. Allergic reactions to IgE antibodies can be severe and cause anaphylactic shock and even death.
There is another antibody, Immunoglobulin G (IgG), that can also cause allergic responses but the reactions are delayed. This delay may make it difficult to identify the specific allergen that is causing the reaction and the discomfort may not be recognized as an allergy. An IgG response may not occur until hours or even days after exposure to the allergen. Symptoms may include headache, nausea, irritable bowel syndrome or other digestive issues, seizures or hyperactivity, making diagnosis difficult.
Not so long ago people, including many children, were subjected to hundreds of needle pricks containing different possible allergens to determine which ones caused the strongest reactions but this method is ineffective for IgG allergies due to the delayed reaction. A simple blood draw can look for specific antibodies to hundreds of substances using only one needle. The presence of the IgG and/or IgE antibodies will identify the allergen so that it can be avoided or eliminated from the diet.
WHY SHOULD I GET THIS EXPANDED FOD ALLERGY PANEL TEST?
Are you experiencing headache, nausea or irritable bowel syndrome without an obvious cause? Do you or your child struggle with hypoactivity or hyperactivity? Are you obese or having difficulty losing weight?
Trying to identify the cause of chronic discomfort can be complicated when it doesn’t seem linked to a specific food or substance, but an allergy test can help. Pinpointing specific foods, additives, or environmental substances that should be avoided can produce dramatic relief of uncomfortable symptoms.
Up to 50 million Americans, including millions of children, suffer from allergies. Allergies are a major cause of illness in the United States and can be so severe that they can lead to death. While IgE allergic responses can be treated with antihistamines to block the production of the antibodies, IgG antibodies provide long-term resistance to infection and live longer in our systems. The only treatment for IgG allergies is to completely eliminate the allergen. Digestive problems may contribute to IgG allergies. Some people suffer from “leaky gut” in which food particles travel outside the intestines causing the body to react to a perceived threat and produce IgG antibodies. Over time the chronic allergic response can lead to a weakened immune system. Dietary and lifestyle changes to avoid the offending food or substance can help you feel better quickly.
OTHER RELEVANT TESTS:
People who purchased the Expanded Food Allergy Panel also considered the Basic Check Up or one of the Sensitivity and Intolerance tests to 50 Functional Foods or Medicinal Herbs or the Comprehensive Platinum Panel.
The test results will provide a report that graphically represents foods and substances in groups:
Green: Indicates acceptable foods or substances / not a significant reaction
Yellow: Indicates a low reaction and these items should be avoided if possible
Orange: Indicates a moderate reaction and these items should be avoided for a minimum of 3-6 months
Red: Indicates a high reaction and these items should be avoided for a minimum of 6 months. For a strong IgE response the food should be completely avoided indefinitely.
WHAT TYPE OF PHYSICIAN SHOULD I SEE BASED ON MY TEST RESULTS?
You should see your primary care physician, an allergist or a gastroenterologist.
