"We are excited to finally offer one of the most important tests you could do for yourself and your loved ones and, in most cases, a huge part of the cost will be reimbursable through most insurance carriers," explains Peck. "Your results will give you very important clues to determine if your diet and nutritional supplementation program is working for you and to help fine tune your nutritional program."

Available Labs


Jeannie Peck, a traditional naturopath and functional nutrition clinician with Health by Design Natural Clinic, in Leola, is offering patented micronutrient tests by SpectraCell Laboratories to measure the function of selected vitamins, minerals, antioxidants and other essential micronutrients within the white blood cells. The test components are reimbursable by most insurance carriers.

Health by Design offers a variety of lab tests, including hormone, parasites, Mediator Release Test (MRT) Leap for food and chemical sensitivities, intestinal permeability, gluten reactivity, gluten-associated cross reactive foods, chemical immune reactivity, heavy metal and minerals. The clinic educates clients about how their body works and what the results of the lab tests may mean for their health.

Food Sensitivities: An Under Diagnosed Source of Inflammation & Symptoms


Food Sensitivities

We see clients every day suffering from the inflammatory effects of food and food-chemical sensitivities. Food-induced inflammation is so relevant to the health of so many, that its importance cannot be overstated. Food sensitivities represent an important source of inflammation in chronic inflammatory conditions such as:

  • Irritable bowel
  • Migraine
  • Fibromyalgia
  • Attention deficit
  • Hyperactivity
  • Obesity
  • And many other challenging conditions

Reactivity to gluten is just one potential part of the inflammatory puzzle. We know through our experience with tens of thousands of food sensitive clients that even so called "anti-inflammatory" foods, such as salmon, blueberries, parsley, garlic, lettuce, even turmeric and ginger, and virtually every other "healthy" food can trigger inflammatory reactions that contribute to illness.

The Patented MRT®: The Most Effective Way to Identify Hidden Inflammatory Foods


Mediator Release Testing

Despite all the immunologic and clinical complexities associated with food sensitivities, the scientific fact is that white blood cells are always involved in food-induced inflammatory reactions. It's the cytokines, prostaglandins, leukotrienes and other mediators released from various white cells that cause every negative effect you suffer.

Through Oxford, the patented Mediator Release Test (MRT®:) delivers unparalleled information that no other blood test or approach provides. MRT®: is a functional assessment of the inflammatory response that takes into consideration the widest range of sensitivity mechanisms.

The most common blood test used to identify sensitive foods (ELISA IgG) can only detect one lesser kind of sensitivity reaction (Type 3, which covers only about 25% of food sensitivity reactdions). In addition, IgG testing can't identify reactions to food-chemicals. The MRT accounts for both Type 3 and the more common Type 4 pathways, identifying reactions to food chemicals, translating to faster and more complete relief.

"I have worked with hundreds of clients with food and chemical sensitivities. Reviewing the MRT results, incorporating the LEAP meal plan, and recommending specific nutrients to help combat inflammatory responses in the gut, produces the most complete results in the quickest time possible."

  • Micronutrient Testing

    A patented micronutrient tests by SpectraCell Laboratories measures the function of selected vitamins, minerals, antioxidants and other essential micronutrients within the white blood cells. The test components are reimbursable by most insurance carriers.

  • Hair Tissue Mineral Analysis

    Your hair contains all the minerals present in your body, including nutritional minerals as well as toxic heavy metals. Hair mineral analysis is a laboratory test that measures this mineral content in the hair, providing a vivid picture of your internal environment.

  • Functional Adrenal Stress Profile

    A saliva hormone test which includes cortisol, DHEA-S, estradiol, estriol, testosterone, melatonin and progesterone and evaluates the impact of chronic stress on endocrine function by measuring bioactive hormones.

  • Thyroid Panel

    A complete thyroid panel including TSH, FT4, FT3, TT4, TT3, TPO Ab, TAA Ab, FTI

  • Cholesterol, Glucose, Kidney and Liver Function

  • Gastrointestinal Pathogens

    Digestive tract infections and inflammation must be analyzed to determine a patient's functional health status. This involves collection of a stool sample taken in the privacy of your home and shipped to a lab that uses advanced staining and antigen techniques to recover pathogens such as ova and parasites and antibodies to the antigens of Giardia lamblia, Cryptosporidium parvum, and Entamoeba histolytica. This test also screens for bacteria, fungi, yeasts, occult blood, Clostridium difficile: colitis toxins A & B, and H. pylori antigen.

  • Gluten-Associated Cross-Reactive Foods & Foods Sensitivity

  • Wheat/Gluten Proteome Reactivity & Autoimmunity

    We use outside labs to perform all tests. Our services and products and the claims made have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease.
