Functional Allergy and Nutrition (FAN) Panel

Functional Allergy and Nutrition (FAN) Panel: A New Tool for Determining Optimal Diets for Patients

The Functional Allergy and Nutrition (FAN) Panel is a comprehensive panel of tests that GPL has created to help practitioners determine personalized, optimal diets for their patients. This panel includes our IgG Food MAP with Candida + Yeast (190 foods), Dipeptidyl Peptidase IV (DPP-IV) Test, Iron + Total Iron-Binding Capacity Test, and Homocysteine Test. Together these tests will provide indicators of specific allergies and sensitivities, as well as clinically relevant nutritional deficiencies and excesses that are common in the population, but not commonly tested. All of these tests are blood serum tests and can be easily run on the same sample.

Total specimen requirement: 3 mL of serum

IgG Food MAP with Candida + Yeast
(190 foods)

Immunoglobulin G (IgG) testing is a useful guide for structuring elimination diets for patients with neurological, gastrointestinal, movement, and behavioral disorders. High IgG antibody levels have frequently been found in children with diabetes mellitus, Crohn’s disease, celiac disease, and in those considered to be obese.

Dipeptidyl Peptidase IV (DPP-IV) Test

Dipeptidyl Peptidase IV or DPP-IV is a critical enzyme that regulates a wide variety of physiological processes including eating, digestion, immune function, pain perception, growth, infection, and many others. Food proteins that have the highest amounts of these DPP-IV inhibitors are cow’s milk and wheat.

Homocysteine Test

Excess homocysteine is a key factor in cardiovascular disease, psychiatric disorders, cancer, hip fractures, and Alzheimer’s disease. Factors that increase homocysteine include genetic deficiencies of enzymes in the transulfuration methylation cycle such as MTHFR, CBS, BHMT and others, a diet high in methionine, or deficiencies of folate.

Iron + Iron-Binding Capacity Test

Iron excess is a very common problem in adult men and in post-menopausal women. Iron excess can result from excessive iron supplementation or excessive intake of red meat. Men or post-menopausal women should avoid iron supplementation unless there are conditions causing excessive blood loss..
