ALLERGY & SENSITIVITY TESTING
Food & Environmental
If a person has a true allergy it means there is a measurable amount of circulating, allergen-specific IgE antibody in the blood. Some people exhibit allergy-like symptoms yet there is no allergen specific antibody found in their blood. There are environmental and food substances that people have a sensitivity to but not an allergy although exhibiting similar symptoms.
A major difference between an allergy and a sensitivity is that the latter may be more temporary and will dissipate sooner than upon eliminating the exposure to or consumption of the substance in question. Our tests provide our patients with a range of how sensitive your body is to certain tests. This situation occurs frequently with cats where a person exhibits allergy symptoms if they come in contact with cats but there is no significant level of cat allergen IgE in their blood. Removing oneself from contact or the vicinity of the cat you should notice the allergy-like symptoms subsiding rather quickly. In a true allergy the symptoms would remain for quite some time if the immune system was triggered sufficiently to start producing IgE antibodies.
Some people have a medical condition known as intolerance i.e. lactose intolerance and gluten intolerance. The symptoms associated with these conditions are similar to some allergy symptoms but a physician will have to perform specialized tests of the gastrointestinal system to diagnose these.
IgE (or immunoglobulin E) allergies are immediate responses to a foreign substance that has entered the body. These foreign substances can come from food or inhalation. IgE allergies can cause very serious symptoms like difficulty breathing, swelling, and hives. In even more serious cases IgE reactions can lead to anaphylactic shock. This test measures the blood level of IgE, one of the five subclasses of antibodies. Antibodies are proteins made by the immune system that attack antigens, such as bacteria, viruses, and allergens. IgE antibodies are found in the lungs, skin, and mucous membranes. They are associated mainly with allergic reactions (when the immune system overreacts to environmental antigens such as pollen or pet dander) and parasitic infections.
IgG (of immunoglobulin G) have a much longer half-life than the traditional IgE allergy. This is where food sensitivities come in because they are much more subtle and most people live with them for years, if not their entire lives. A food sensitivity is an adverse reaction to a food with no antigen-antibody response. Symptoms, ranging from headache and nausea to seizure and hyperactivity, or simply just fatigue, bloating, mood changes or dark circles under the eyes. They may occur hours or even days after the offending food has been ingested. The degree and severity of symptoms vary greatly because of the genetic makeup of the individual. The complete elimination of IgG positive foods may bring about important improvements in symptoms of irritable bowel syndrome, autism, AD (H) D, cystic fibrosis, rheumatoid arthritis, and epilepsy as demonstrated in numerous clinical studies.
