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..

Verified customer reviews for expert-curated supplements and nutritional guidance by Stephen Heuer
"Stephen Heuer has extensive knowledge in helping you recover from any health challenge you are facing. I have had issues with my kidneys and Stephen has been invaluable in helping my health get better. You would do yourself a favor by getting a consultation from him for whatever health challenges you are facing."
"I've been enjoying the benefits of Synergy One and Green Meadow Whey for years now. At 71, they truly have made me feel 10 years younger — increased energy, better skin, rejuvenated hair growth, and increased libido being the primary benefits."
"I have used Synergy One for twenty years! I tried getting off it but noticed joint pain, so I got right back on. I will always use this product because it has raised my DHEA level and it seems to make my HRT work better."
"I highly recommend Steven for all his products. I was sick for 5 days and my husband gave him a call — he gave some supplements plus the Green Meadow Whey protein and the following day I was getting better and my energy went back to normal in a few days."
"After taking his recommended supplements, I've lost weight and improved gut health. The specific probiotics working in tandem with the recommended diet improved the health of my gut bacteria and made it extremely easy for me to keep from gaining the weight back."
"I had a hyperthyroid with shakes and fatigue — doctors wanted to put me on medicine for life. Steven put me on nutrition that completely healed my thyroid. The doctors could not believe the blood count and were shocked that another way of treatment was available."
