Test 104 micronutrients, botanicals, and antioxidants to nourish and protect your body at the cellular level. This test can also be used to customize supplements and/or I.V.’s.
This test may help with:
If we could give every individual the right amount of nourishment and exercise, not too little and not too much, we would have the safest way to health. (Hippocrates)
People are often confused as to whether or not their supplements are truly benefiting them. This test answers those questions.
Micronutrients counteract stress and improve resistance to environmental pollution, toxins, and drugs, which varies from person to person. Many factors, such as lifestyle, genetics, pregnancy, recent infection, sleep patterns, overexertion in sports, age, gender, and other factors may play a role in your nutritional status and needs.
The Cellular Nutrition Assay (CNA) reflects how your immune cells respond to and are protected by specific micronutrients and antioxidants all of which is based on your biochemical individuality.
Thus, the CNA tells you what your cells need.
Everybody’s nutritional needs are different. The Cellular Nutrition Assays (CNA) examine how your cells respond to specific nutrients – not just whether you are within “normal population ranges”. The CNA provides the basis for personalized foods and supplements tailored to your unique needs.
The Previ Expert Package will take into account all laboratory findings for your personalized diet and supplement plan.
Nutrient stores in cells reflect long-term nutritional status and have the most functional impact. We analyze the direct response of your immune cells (lymphocytes) when individual micronutrients are added to them. When we see increased metabolism of your immune cells it may indicate a micronutrient insufficiency.
The Redox Assay or your “cell stress test” reflects your antioxidant capacity, in other words, your cells’ ability to resist oxidative damage.
The cell protection part of the test indicates which nutrients should be considered to protect your immune cells, resist oxidative damage, and improve your overall antioxidant capacity (Redox).
Results are actionable, easy to understand, and meaningful.
A simple blood draw is needed.
Nutrients are highlighted according to your cellular responses. Descriptions of each “insufficient” nutrient and “protective” antioxidant are provided along with specific foods to emphasize in your diet.
We recommend that this test be used as part of a comprehensive nutritional assessment with individualized guidance as provided with the Previ Expert Package.

Let food be thy medicine! Functional food sensitivity testing at the cellular level shows how your immune cells respond to foods.
Add on Alcat Comprehensive

Food sensitivity may be associated with:
The impact of food sensitivity is easily underestimated. The Alcat Test uncovers how food, even supposedly healthy foods, may affect your wellbeing.
Are you confused by all the dietary advice? Gluten-free, Paleo, dairy-free, no nightshades, no caffeine, vegan, no grains… ever feel like you’re constantly trying to pinpoint which foods you should and shouldn’t eat?
You are unique. One way to personalize your diet with the foods that are right for you is to take the Alcat functional food sensitivity test.
This anti-inflammatory diet may support the immune system, detoxification and metabolism – a prerequisite for health, wellness and performance.
Our functional food sensitivity is a biological immune cell activation. Detected cell changes in volume, size and number are associated with cell activation potentially causing inflammation.

Immune cell activation is the cause of inflammation
The immune system is a double edged sword. It should react appropriately and protect against infection when confronted with harmful invaders.
The above figure shows the defense reaction of an immune cell (neutrophil/eosinophil granulocyte) causing inflammation. Beside pathogens such reactions can also be induced by foods, toxins or chemicals. The scientific term is DAMP, danger/damage associated molecular pattern. Adverse reactions to foods are found to be a factor in chronic and cardio-metabolic diseases, or autoimmunity.
The Alcat Test does NOT measure “true” food allergy classic allergy type 1) where symptom onset is immediate and acute. The Alcat Test identifies foods which may cause delayed type hypersensitivities that are usually chronic and low grade. Therefore, you may not be aware that chronic symptoms may be associated by foods regularly consumed.
A review of test results with your Previ Nutrition Counselor is included.
Your blood sample is sent to the laboratory. The sample first goes through a multi-step quality assurance process. During testing, your immune cells are confronted with foods and/or items including additives, colorings, molds, medicinal herbs, and chemical agents.

After testing, the results are presented in a clear and easy to read color-coded format, showing you which foods/substances to which your cells had a severe, moderate , mild, or no reaction.
A suggested dietary rotation plan is provided. The test result review is included.

The methylation-detoxification profile is a genetic test for important metabolic pathways, detoxification, and hormone balance.
Add on Cellular Nutrition Assays

The genetic test may help with:
More than 50% of people may be affected by genetic variants in the methylation pathway. Fortunately gene variants can be supported with proper nutrition and the right supplementation.
Methyl groups can act as gene regulators. They are biochemical on-and-off switches of gene expression. They control enzymatic reactions, impact mood and neurotransmitter balance, protect against chronic degenerative disease by reducing inflammatory processes, transform toxins into forms that are more readily excreted, impact tissue healing, and protect cells from oxidative stress.
Thus, methylation can play an important role in many health conditions.
You’re unique. Eat like it.
Vitamins, minerals, nutrients, coenzymes, and botanicals can only do their job as desired on the basis of functioning methylation.
Essential processes of the body to maintain health and self-healing are influenced by methyl groups. If methyl groups are in short supply, the body has difficulty controlling these functions. You become ”out of balance”.
Identifying your genetic variants can help determine what nutrient support you need.
The Previ Expert Package will take into account all laboratory findings for your personalized nutrition and supplement plan.
The Methyl Detox Profile test components:
The genes are analyzed using real time SSP-PCR (polymerase chain reaction with sequence-specific primers) followed by melt curve analysis.
The methylation process and the functional status of the methylation pathway is profound and complex.
The Methyl Detox Profile provides an easy-to-understand test report which is both clear and patient friendly.

A simple swab sample or blood draw is needed.
Test results include expert clinician commentaries and include personalized recommendations for diet, nutrient supplementation, or IV nutrient therapy.
We recommend that this test be used as part of a comprehensive nutritional assessment with individualized guidance as provided with the Previ Expert Package.

Test your compatibility to medicinal herbs and functional foods
The test may help to
Medicinal herbs, functional foods and botanicals are widely used in supplements, teas, creams, tinctures, cosmetics… even in functional foods, e.g. protein bars.
The potency of botanicals is easily underestimated. Our testing uncovers how the intake of supposedly healthy food supplements or natural medicine may actually impede your health goals because they may not be compatible:
Taking the “extra vitamin kick” or botanicals does not always have the beneficial effect that is hoped for. The active ingredients are very potent and should not be underestimated.
The biologically active plant ingredients in adaptogens are intended to help people “adapt” to increased physical and emotional stress. Adaptogens can even have multiple beneficial effects, e.g. simultaneously calming and vitalizing or stress-reducing and performance- enhancing. So, it is important that you use the right ones for you.
The functional Alcat sensitivity test evaluates if immune cell reaction against phytoceuticals are present. If an excessive cellular immune response (sensitivity or intolerance) is identified, the consumption should be avoided.
So that you get the most out of taking supplements, medicinal herb or functional food it is important to determine whether a substance is a friend or foe of your immune cells.
If you show a reaction in your Alcat Intolerance Test to medicinal herbs or functional foods, you should definitely avoid the substance affected.
Your Previ Expert counselor will take into account your lab findings to provide you with a personalized nutrition and supplement plan.
Functional phytoceutical intolerance testing
This highly specialized functional Alcat phytoceutical sensitivity test is based on the same principle as that of the Alcat Test for food sensitivity, to assess whether immune cell reactions are present or not. If a “foe” is identified in form of an excessive cellular immune response (intolerance), the intake should be avoided.
Phytoceutical intolerance test results are easy to understand, actionable, and meaningful.

A simple blood draw is needed.
Alcat Test results are categorized by your individual degree of cellular reactivity (severe, moderate, mild, or non-reactive) and reported in an easy to read color-coded format.
For this highly specialized test panel we recommend that this test be used as part of a comprehensive nutritional assessment with individualized guidance as provided with the Previ Expert Package.

Functional Laboratory Testing aimed at personalized nutrition and prevention of chronic inflammation and autoimmune disease.
Functional testing can meet your unique needs and does not use population average standards. Instead, each test serves as its own baseline.
The Alcat food sensitivity or intolerance test identifies adverse reactions to dietary items. Especially innate immune cells are a reliable indicator of a pro-inflammatory reaction – they cause, initiate and maintain inflammation.
Immune cells can also be used as a biomarker for the absorption and metabolism of nutrients. The Cellular Nutrition Assays (CNA) show which nutrients, botanicals, antioxidants etc. are insufficient and which are beneficial for an individual.
The functional nutrition tests can be complimented using indicators or risk assessment for disease processes: for example, CICA for intestinal complaints or the telomere length test to determine the ratio between actual age and the so-called biological age.
