Blood Tests for Food Allergies

Like urine analysis, there are many types. We usually recommend clients to do blood tests for food allergies and/or inhalant allergies. We specifically test for the following IgE and IgG type of food allergies.


IgE Food and inhalant allergies

IgE allergy, often called hypersensitivity, refers to undesirable, damaging, and sometimes fatal reactions produced by the immune system. Some people can tolerate a large degree of allergens without ever experiencing any outward symptoms while others may only require a very minute amount of exposure to allergens before symptoms are expressed. The degree and severity of symptoms vary because of the genetic makeup of the individual. Allergic type reactions require a pre-sensitized immune state more likely to develop allergic reactions. A person who has a classic allergy usually develops redness, swelling, and heat in the body as a result of the elevated blood levels of Immunoglobulin E (IgE). Contrary to popular belief, the symptoms produced by IgE can be subtle and similar to those seen in other conditions. This potential confusion makes diagnostic testing very important in recognizing the disorder known as allergy. When symptoms of allergy occur internally, the symptoms may be specific to the failing organ affected by the inflammation, such as the case with asthma. Approximately 80% of children with asthma also have documented food allergies. Other allergic conditions, such as nasal allergies or eczema, are often also present. Allergic asthma often goes into remission in early adulthood. However, in 75% of cases, the asthma reappears later.

IgG Food allergies

IgG testing is a useful guide in structuring elimination diets for many chronic conditions. Individuals with neurological, gastrointestinal, and movement disorders often suffer from IgG food allergies. These people may continue to compulsively eat the offending food, unaware of potential effects. Complete elimination of potential problem foods from the diet may bring about striking improvements in health status, mood, energy, and even behavior. IgG antibodies are the antibodies that provide long term resistance to infections after immunizations. These antibodies have a much longer half life than traditional IgE allergy and function in a much different capacity with immune cells. This different function of IgG causes the symptoms of the allergy to be delayed. Thus, symptoms may occur hours or even days after the offending food has been ingested. Some people can tolerate a large degree of food without ever experiencing any outward symptoms. Others may only require a minute amount of food before symptoms are expressed. The degree and severity of symptoms vary because of the genetic makeup of the individual. Clinical studies have recently been published which demonstrate that 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.
