Food Allergy Testing

Food Allergy Testing
Forrest Health Online offers at home and laboratory clinical testing, interpretation and natural vitamin, herbal and homeopathic therapies for food allergies.

We offer several Food Allergy Tests to choose from depending on how many allergens you wish to test as well as how the test is done. The most comprehensive and accurate is the the LEAP MRT. This is a state-of-the art test and is the one we do in our office the most.

Food Allergies

Researchers estimate that at least 60% of the U.S. population suffers from unsuspected food reactions that can cause or complicate health problems. Symptoms can be extraordinarily diverse, ranging from arthritis to eczema to migraines. For that reason, many health professionals routinely consider food allergies or intolerances when evaluating a patient's health problems.

The less common but widely recognized atopic food sensitivities, such as an immediate reaction to peanuts or shell fish, are IgE-mediated responses.

IgG antibodies are associated with non-atopic or "delayed" food reactions that can worsen or contribute to many different health problems. These reactions are more difficult to notice since they can occur hours or even days after consumption of an offending food. In some cases, a person may eat a food for several days before developing a reaction to it, so they may not realize the link between the food and their symptoms. These "hidden" food allergies are caused by increasing IgG antibody blood levels in reaction to specific foods. Often the offenders are frequently eaten foods that are hard to avoid, such as milk, corn, and wheat. Simultaneous high levels of many IgG food-specific antibodies are generally related to intestinal hyperpermeability.

Food sensitivities can occur at any age, triggering many different symptoms and contributing to a variety of disorders, including:

  • Inflammatory bowel disease
  • Fatigue
  • Migraine
  • Skin problems
  • Rheumatoid arthritis
  • Sinusitis
  • Recurrent ear infections


The LEAP Program is a highly effective Disease Management Program that combines patented blood testing technology with customized software, experience & know-how, to provide patients and physicians a complete method of managing Irritable Bowel Syndrome and Migraine.

2.  Bloodspot IgG Food Antibody Profile:
From a simple finger stick, the Bloodspot IgG Food Antibody Profile measures levels of IgG antibodies specific to 30 commonly offending foods. It clearly identifies those foods that may be causing health problems, helping to achieve positive outcomes sooner, even when combined with elimination/provocation testing.

We offer several finger prick blood tests to choose from, Allergy Testing 96 Food, Allergy Testing 24 Herb & Spice, Allergy Testing Blood Spot.

  • Detects delayed or hidden food sensitivities
  • Test is done at home with a finger prick.
  • Is so easy to use that patients can even do it at home
  • Measures the IgG immune response to the thirty most commonly reactive foods
  • Includes a patient-specific rotation/elimination diet booklet.

When you order a test from us we will send you the test kits with free mailers. Samples are taken at home  or the lab and then mailed directly to the testing laboratory. Results are reviewed by Dr. Forrest and then sent to you.
