Food Intolerance Testing

Food Intolerance Testing or IgG/IgE RAST Testing Options

The ALCAT Test is NOT an “allergy” or IgE test. The ALCAT is the most effective and comprehensive sensitivity/intolerance test available. The ALCAT differs from other food allergy or intolerance tests as it accurately and objectively measures leukocyte cellular reactivity in whole blood, which is a final common pathway of all mechanisms. The test utilizes electronic, state of the art, hematological instrumentation. Standard allergy tests, such as skin testing or RAST are not accurate for delayed type reactions to foods and chemicals. They measure only a single mechanism, such as the effect of mast cell release of histamine or the presence of allergen specific IgE molecules. Delayed reactions to foods and chemicals are NOT IgE mediated.

The ALCAT Test also differs from standard IgG tests in that they rely exclusively on one immune pathway, serum levels of immunoglobulin G (IgG). In fact, high food specific IgG titers are indicative only of exposure, not necessarily intolerance. The ALCAT Test reproducibly measures the final common pathway of all pathogenic mechanism; whether immune, non-immune, or toxic. It is the only test shown to correlate with clinical symptoms by double blind oral challenges, the gold standard. For over 24 years, the ALCAT Test has provided both patients and healthcare professionals with a tool to successfully overcome a wide variety of conditions, such as digestive disorders, migraines, obesity, chronic fatigue, skin disorders and arthritis, which result from food and chemical sensitivities.
