Micronutrient Test

Our intolerance test covers over 650 potential substances. These include commonly mentioned groups such as dairy products (lactose), fruit (fructose), grains (gluten), histamine-rich foods, as well as vegetables, nuts, spices, additives, and much more. You'll receive practical guidance on which substances might deserve special attention in your everyday life.

With an allergy, the immune system reacts to certain substances and can trigger stronger physical reactions. Individual food reactions typically don't involve the immune system and mostly show up in digestion or general physical well-being. Our test doesn't replace a medical diagnosis but can offer useful pointers for your everyday life.

Some people notice reactions after eating certain foods — an unusual feeling in the stomach, bloating, nausea, diarrhea, or constipation. These can appear hours later, which makes it harder to identify the cause. In our survey, nearly 18% of participants personally reported intolerances — one of the more frequently mentioned topics.³

You cut off 10–20 hairs, put them into a small paper or plastic bag and stick it onto the submission form from your order confirmation at the marked spot. You send both to us by post. At the same time, you fill in our online questionnaire with your personal order number. Your sample is then analysed and you receive your written evaluation as a PDF by email.

The products offered at www.medicross.com — such as „Intolerance Test“, „Micronutrient Test“, „Microplastic Test“ or „Heavy Metal Test“, along with their variants for pets — serve exclusively as individual, complementary wellness orientation. The names are used in a non-medical, everyday context. Our tests are based on alternative methods that do not involve any biochemical, molecular-biological, or cellular analysis. They have no medical purpose and are not equivalent to conventional medical lab tests or in-vitro diagnostics under EU Regulation (EU) 2017/746 (IVDR). The results are intended for subjective reflection on individual resonance patterns — in humans as well as animals — and do not replace medical or veterinary assessment. Our tests are expressly not intended to determine medically relevant parameters such as allergies or deficiency conditions. They constitute no diagnosis, contain no treatment recommendation, and are not suitable for the prevention, treatment, or monitoring of illnesses. We expressly point out that our tests and content: do not constitute or replace a medical diagnosis; are not intended to detect, treat, monitor, or prevent illnesses or health disorders; are not suitable for self-medication or therapy adjustment. None of the content represents a healing promise or efficacy claim. Diagnoses and treatment decisions may only be made by licensed medical doctors. For any health-related questions, qualified medical advice must always be sought. Every individual acts on their own responsibility. All product images and illustrations are symbolic and have no diagnostic or scientific value. The micronutrient analysis results in a need-percentage value, which is to be understood as a guide value. Expressly noted: this is not about deficiency symptoms. In intolerance tests, all parameters that do not react beyond a threshold value are hidden. The intolerance test does not include any test for allergies.

Our approach is based on holistic and complementary ways of thinking, without making medical diagnoses or healing promises. Rather, we want to support you in shaping your lifestyle individually, consciously, and on your own terms. You can find more details in our Disclaimer*

Please note that substances marked with ¹ are optional and can be added to your evaluation for a surcharge. During checkout you have the option to select this add-on to include the desired substances in your personal analysis. ² Sources: Robert Koch Institute. (2016).

Yes — dyed, tinted, or chemically treated hair doesn't affect the result. You can send it in without any concerns. The same applies to hair after a perm, straightening, bleaching, or highlights. The only requirement is that it's clean and dry.

Cut off 10–20 hairs as close to the scalp as possible and put them into a small paper or plastic bag. Stick the bag onto your submission form (the PDF from your order confirmation) at the marked spot. Please never put loose hairs into the envelope – inside the bag the sample stays protected during transport. Then fold the submission form, put it into a normal envelope and send it by post to the address given in the confirmation. At the same time, fill in the online questionnaire at fragebogen.medicross.com with your order number.

We need 10 to 20 hairs for a reliable evaluation. The hairs should be freshly cut, clean, and dry. If you don't have enough head hair, you can also use body hair.

Hair length doesn't matter. Even very short hairs of just a few millimeters work, as long as you can gather the required 10–20 hairs. What counts is the number, not the length.

The test works perfectly fine even with a bald head, very thin hair, or bald patches. Use body hair instead — beard, chest, underarm, or leg hair work just as well as head hair. Combed-out or fallen hair without roots is also suitable, as long as you can gather the minimum of 10–20 hairs.

Once your hair sample arrives with us, the evaluation usually takes around 18 business days. With the Express service, this time is shortened accordingly. You'll automatically receive an email as soon as your personal evaluation is ready.

You receive your evaluation as a PDF document by email. That way you can open it on your phone, tablet, or computer and print it yourself if you wish. There's no additional postal delivery.

Your evaluation uses clear scales and plain terms: „Deficiency“ points to areas where our analysis shows a clearly pronounced pattern. „Need“ describes a more moderate signal — where it can be worth paying more conscious attention to certain food groups or routines in your daily life. The percentage values next to them express the intensity of the individual resonance. Both terms are meant as an impulse for reflection and don't replace a medical diagnosis.

Our team of nutritional scientists is available by email or phone. You can also book a consultation directly if you'd like to go through your results together.

Choose the Combo Test in our online shop, add it to your cart, and follow the checkout process. After completion, you'll receive a confirmation email with your personal submission sheet to print yourself and all further information.

No, we deliberately do not ship a test kit. Instead, after your order you receive your personal submission form as a PDF by email to print out yourself. You put your hair sample into a small paper or plastic bag and stick it onto the printed submission form at the marked spot. You put both into a normal envelope and send it to us. This saves shipping time and packaging waste, and speeds up the process for you.

Depending on the payment method, it can take up to 24 hours for the confirmation with the submission sheet to reach you. Please also check your spam or promotions folder first. If after 24 hours you still haven't found it, write to us at info@medicross.com — we'll send you the confirmation manually.

Each Combo Test is designed for one person, since the evaluation is created individually. If you'd like to test a partner, children, or other people, please order a separate test per person.

You have a 14-day right of withdrawal after your order — but only as long as you haven't downloaded your submission sheet yet. With the download of the submission sheet, the service begins and the right of withdrawal expires early. Once the 14-day period has passed or the submission sheet has already been downloaded, cancellation is no longer possible. As long as both conditions are met, simply send us an email with your order number to info@medicross.com.

During phases of intense physical exertion, your individual need for vitamins, minerals, and trace elements can change. Nearly half of our survey participants regularly do endurance sports, and about a third also do strength training.³ The micronutrient analysis can give athletes impulses to reflect more consciously on their supply — complementing training and nutrition plans, but without replacing sports-medicine diagnostics.

For any questions about nutrition during this phase of life, please always consult your doctor, midwife, or a qualified nutritional advisor.

Since our procedure isn't a biochemical blood measurement, you can usually take the test even while on medication — for example cortisone, the pill, antibiotics, antidepressants, painkillers, or thyroid medication. Please list your current medications and supplements in the online questionnaire — this helps us with the assessment. Any change to your medication should be discussed exclusively with your treating physician.
