How it works

A small sample of your blood is sent to the laboratory overnight. Upon receiving the sample, the blood goes through a multi-step quality assurance process. During testing, your white blood cells are tested against foods and other substances in a process known as flow cytometry and cell impedance methodology. After testing, the results are presented in a clear and easy to read color-coded format.

The power of knowing

There is a new paradigm in health and medicine - personalization. Health can be improved and maintained by knowing how food plays a role in your body.

The Alcat Test enables you to take advantage of leading technology to create a personalized nutrition plan resulting in benefits that can be seen and felt.

The results from the Alcat Test can help determine which foods and other substances may trigger unwanted inflammation. The personalized nutrition plan based on your immune response can assist with food choices that are better for your health and well-being. When complying with the Alcat Test results, many clinical symptoms associated with food sensitivity may be substantially improved or possibly prevented altogether1-6.

Good to know

The Alcat Test has been independently evaluated and demonstrated a high degree of benefit 2, 6. Positive results related to a broad range of symptoms have been reported in more than 30 published studies.

Sensitivity vs. Allergy

An allergy is a reaction that triggers the release of antibodies that results in immediate symptom onset. A true food allergy causes an immune response that can affect multiple organs and in some cases, be severe or even life threatening. Food sensitivity symptoms are delayed and are typically limited to digestive problems, but they can lead to chronic inflammatory health issues.

Associated Conditions

Symptoms such as migraines, aching joints, fatigue, gastrointestinal disorders, and others have been linked to food sensitivity and chronic inflammation. The Alcat Test is designed to assess sensitivities to over 450 food, chemical and environmental substances. These sensitivities are shown to be associated with both acute and chronic conditions.

  • Gastrointestinal disorders, such as Irritable Bowel Syndrome (IBS), indigestion, constipation, nausea, diarrhea, bloating, ulcerative colitis, Crohn's Disease1, 3, 7-9
  • Metabolic disorders, such as obesity, Type II diabetes, inabilitiy to lose weight 2, 7, 10, 11
  • Inflammatory conditions, such as eczema, psoriasis, arthritis or asthma, autoimmune disorders 1, 5, 9, 12-15
  • Others, such as fatigue, headache, migraine, cognitive impairment 9, 16

Clear test results

Utilizing Alcat Test results to create an individualized nutrition plan, based on your immune system, enables you to make food choices that are better suited for your health and well-being. With the Alcat Test many clinical symptoms associated with food and chemical sensitivities can be substantially improved or possibly prevented altogether.

Test results include:

  • Easy to understand color-coded test report.
  • Foods to avoid list.
  • Comprehensive "Understanding your Alcat Test Results" guidebook.
  • Personalized rotation plan.
  • Practical shopping guide and restaurant card.

Test over 450 items

Over 450 individual foods, additives, colorings, molds, functional foods, medicinal herbs and chemical substances (such as environmental, chemical, pharmaceutical substances) can be tested.

Note: The Alcat Test does not make a medical diagnosis nor is it a substitute for health or medical advice. If you have a medical condition you should seek a qualified healthcare practitioner.

The laboratory analysis includes the immune biological reactions of the white blood cells. The Alcat Test® does not measure food allergies (type 1/IgE). Since these reactions can be serious, you should seek the help of an allergy specialist if you suspect or have food allergies. The Alcat Test does not measure enzyme induced intolerance to lactose, fructose or histamine. It does not measure IgG antibodies.
