allergy testing

[Guest guest]

Are you writing about the food panel/IgG/ELISA type test or the

RAST/classic allergy type of test? If it's the former, then yes, the

test is effected by what foods have been recently eaten. And if

someone is consuming a major trigger food, then minor food problems

escalate and will result in high reactions, too. It's just a

snapshot of one point in time. It's very helpful, but not 100%

accurate (so I'm told. Actually, my son's test was right on.)

I, too, never saw reactions to particular foods prior to testing and

the gfcf diet. Maybe because my son was mess all the time. But once

gfcf and improving, the other food and additive issues became obvious.

In the future, we hope to slowly reintroduce some foods with a low

positve reaction. Other listmates have been able to do so

successfully.

If the tests were for histamine-type reactions (hives, congestion,

anaphylatic shock), I personally wouldn't try anything with a

positive result, not even if I was sitting in the emergency room.

At my continuing ed seminar yesterday, one of the other SLP's (speech

language pathologists) was telling me about a friend of her's, whose son was

initially diagnosed with Autism. The mother didn't believe this and took

matters into her own hands. She found a certain type of blood test that

tests for different allergies that don't show up in scratch tests. Here's

the info....

Hmmmm it says that allergies can even cause ADD.....hmmmmmmmmmm

Food Allergy Profiles

IgG Food Antibody Assay

Food Allergies can occur at any age, triggering many symptoms and

contributing

to a variety of disorders, including:

.. Rheumatoid Arthritis

.. Skin Problems

.. Fatigue

.. Migraine

.. Inflammatory Bowel

.. Attention Deficit Disorder

.. Sinusitis

.. Recurrent Ear Infections

Why test for IgG food allergies?

.. Most Common

IgG response is the most common cause of adverse food reactions.

.. Delayed Symptoms

Patients are often unable to associate symptoms with foods they eat.

.. IgG Food Allergies Underdiagnosed

Identification of offending foods is essential for effective intervention.

.. Patient Compliance

Much easier to identify intolerances than elimination/provocation testing.

.. Negative IgE

Patients with delayed food intolerance often have negative IgE and skin test

results.

What is the IgG Food Antibody Assay?

.. An effective clinical tool to detect delayed or hidden food intolerances.

.. The food allergy test of choice to identify problem foods missed by IgE or

skin testing.

Delayed food reactions often reflect frequent exposure to commonly eaten

foods:

.. Grains

.. Dairy

.. Fish/Shellfish

.. Fruits

.. Nuts/Seeds

.. Vegetables

.. Legumes

.. Meat

.. Poultry

.. Molds

IgG Food Antibody Assay

.. Serum

.. 90 food antigens

.. Includes Aspergillus mold

.. Custom four-day rotation diet

.. Food families exhibiting cross reactivity

Bloodspot IgG Food Allergy

.. Fingerstick Blood Spot

.. 12 food antigens

.. Includes Aspergillus mold

.. Generalized four-day rotation diet

.. Food families exhibiting cross reactivity
