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.
