Blood Allergy (Serum allergy) testing is a unique test for allergens in the body. It is most accurate compared to many non-serum tests. Surely, it is not similar to skin allergy testing at all since it does not introduce foreign substances inside the body to test for allergens. Serum allergy testing tests for allergens already present in the body as a result of consuming foods that contain allergens over the past year. Serum allergy also tests for 36 environmental allergen that a person may have encountered in the past year.
Serum allergy testing offers three panels of testing. Two food allergy tests;
- Serum Associated Allergens Test IgG food panel (A Panel)
- Serum Associated Allergens Test IgE food panel (E Panel)
- one environmental panel (Serum Associated Allergens Test – Inhalants Panel).
While it is possible to order the E and the A panels separately, the E Panel and the A Panel (Serum associated allergens- Food Panel) are best when ordered together as a combined panel for a total of 196 allergens. It is frustrating to order one panel and neglect the other food in the other panel. The serum associated inhalant panel (Environmental Panel) offers five regionally specific inhalants from given regions of the continental USA (NW, SW, W, NE, SE) and matching areas in the world on the same equator level. All assays are in full compliance with rigorous Washington State Department of Health, Health Systems Quality Assurance standards.
PANEL OF TESTS
- E Panel: 96 commonly eaten foods
- A Panel: 96 additional foods and seasonings, with no overlap of the E Panel.
- Combined IgE and IgG4 antibodies are measured.
- Inhalants Panels include common tree, grass, weed, and mold for each specific region.
- All inhalant panels include plants, cat, dog, and mite (environmental) antigens.
Allergy symptoms may be presented disguised in the following symptoms
Estimates of the proportion of the population allergic to foods vary around 50% and this figure has increased over the last 50 years. An increase in the variety of foods eaten as well as increased early exposure to cow’s milk formula and other dairy products such as eggs have both contributed to the rise in food allergies. Symptoms vary widely in people.
The immediate, obvious IgE-mediated food reactions include hives, wheezing, rhinorrhea, vomiting and anaphylaxis.
Delayed or IgG-mediated reactions include non-obvious, chronic symptoms such as headache, digestive complaints, musculoskeletal symptoms and skin disorders such as eczema and psoriasis.
This laboratory measures both IgE and IgG4 antibodies.
Prominent allergist J.C. Breneman once wrote, “food allergy is often overlooked …any patient with confusing, prolonged complaints or poor treatment response might recover amazingly on a week of diagnostic elimination diet.” Consideration of food allergy is a critical component of any comprehensive approach to ill health or for prevention of illness, and an elimination diet approach remains the gold standard for diagnosis of food allergy.
