Unser Anspruch
Was heißt wissenschaftlich bei mybody x?
Gemessen wird an deiner Probe, nicht an einem Fragebogen. Und jeder Wert bekommt nur so viel Bedeutung, wie die Forschung hergibt.
01
Gemessen, nicht geschätzt
Die Probe aus Speichel, Kapillarblut oder Stuhl, die du zu Hause entnimmst, analysiert ein nach ISO 9001 und ISO 13485 zertifiziertes Labor in Deutschland mit etablierten Laborverfahren. Deine Daten werden nach ISO 27001 und DSGVO verarbeitet.
02
Eingeordnet, nicht überhöht
Dein Auswertungsbericht übersetzt Laborergebnisse in verständliche Hinweise für Ernährung und Alltag. Er zeigt, was in einem üblichen Bereich liegt oder normal schwankt, und wo es sich lohnt, genauer hinzusehen. Ein Befund beschreibt einen Zustand, keine Ursache.
03
Mit klarer Grenze
Ein Selbsttest ist kein Diagnoseverfahren und ersetzt keine ärztliche Untersuchung. Wer Warnzeichen bemerkt, macht keinen Test, sondern einen Termin.
Process
How does a test work?
The process is the same for all types of tests.

Three types of tests
What is the difference between DNA, blood, and gut tests?
The three types of tests answer different questions because they measure over different time scales.
- Evaluation: 15–25 business days
DNA never changes
Your DNA doesn’t change. That’s why a DNA analysis is enough once in a lifetime. Your result stays the same; only what we can infer from it grows.
- Evaluation 3–5 business days
Blood now reveals the condition
Blood values change over the course of months. For tracking trends, repeating the test every 3 to 6 months is advisable.
- Analysis: 8–10 business days
Gut responds within weeks
The gut microbiome is the part of your body you can influence yourself most quickly. It makes sense to take a gut test every six to twelve months.
Methods
What methods do we use to analyze your samples?
DNA analysis
Our DNA analyses use SNP genotyping, the targeted testing of over 700,000 predefined individual positions in the genome, known as SNPs. So we don’t sequence your entire genome; instead, we read the specific positions that research has linked to nutrition, metabolism, training, and skin aging.
A DNA analysis from mybody x is not a prediction of disease. Genetic variants describe probabilities across population groups, not certainties for individuals. Predisposition is not destiny: what you do with your results is up to you.
Blood tests
Our blood tests use capillary blood: a few drops from your fingertip that you collect yourself at home. Depending on the test, values such as vitamin D, ferritin, the iron storage marker, or the thyroid hormone TSH are analyzed.
A blood value shows your current state. A single lab value is one piece of an overall diagnosis, not a verdict (paraphrased from IQWiG, 2025). Your report helps you put each value into context. An abnormal value does not automatically mean illness, but is a reason to take a closer look.
Microbiome Analysis
MIKROBIOME tests analyze the stool sample using DNA sequencing: The laboratory reads the genetic material of the bacteria in your sample, also detecting species that cannot be grown in a culture medium. This identifies more than 1,500 bacterial species, from which more than 6,000 microbiome biomarkers are analyzed, including not only the species themselves but also metabolic products and ratios.
The two figures describe different things: more than 1,500 species identified and more than 6,000 markers analyzed from them.
Disclosed in advance
How do you know what data is collected before you buy?
The most common question before a test is: Is my value even included? Three searchable dictionaries disclose the scope of the analysis in advance.

Standards
Which standards does the laboratory follow?
Analyzed in a laboratory in Germany certified to ISO 9001 and ISO 13485. Your data is processed in accordance with ISO 27001 and the GDPR. A certificate safeguards the process, not the truth: it confirms that work is carried out according to audited, documented procedures.
ISO 9001
General laboratory quality management.
ISO 13485
Quality management for medical devices.
ISO 27001
Information security when processing your data.
GDPR
Data protection under European law.
Data
What happens to your sample and your data?
Health data is the most sensitive data there is. That’s why we answer the question of data protection concretely: with fixed deadlines and clear procedures.
Destroyed after two months
Saliva, blood, and stool samples are destroyed two months after the analysis is completed; for DNA tests, the DNA sequence is also destroyed.
Transmitted securely
Your results are transmitted using SSL encryption, and processing complies with the GDPR and ISO 27001.
Your message in the customer portal
You can view your results in your customer portal at mylab.mybody-x.com as a PDF to download.
Borders
What can't our tests do?
No mybody x test is a diagnostic procedure. Our products are not intended to diagnose, treat, cure, or prevent diseases. A DNA analysis does not predict disease or forecast weight loss. A microbiome test does not detect chronic inflammatory bowel disease, tumors, infections, or celiac disease. An abnormal blood test result does not automatically mean that you are ill.
Your doctor remains the authority on diagnosis and treatment. Our reports are designed to help you prepare for that conversation: with results you can bring and questions you can ask.
In 2022, a position paper by the DGE noted that evidence for the effectiveness of gene-based dietary recommendations is still largely lacking (paraphrased from Holzapfel et al., 2022). The honest benefit of a self-test is therefore to give you a starting point and structure for changes you already want to make.

How reliable are the analyses?
Each sample is analyzed in a laboratory in Germany certified to ISO 9001 and ISO 13485; data processing complies with ISO 27001 and the GDPR. The certificates attest to audited, documented processes from sample receipt through to the report. A self-test still does not replace medical diagnosis: an abnormal result is a reason to speak with a doctor, not a diagnosis.
Why is a DNA test done only once, while blood and gut tests are repeated?
Your DNA does not change, so a DNA analysis once in a lifetime is sufficient. Blood values change over months, so for tracking your progress, it makes sense to repeat the test every 3 to 6 months. The gut flora changes within weeks, so a gut test every six to twelve months is advisable.
What happens to my sample and my data?
Saliva, blood, and stool samples are destroyed two months after the analysis is completed; for DNA tests, the DNA sequence is also destroyed. Your results are transmitted using SSL encryption, and processing complies with the GDPR and ISO 27001, the information security standard. You can view your results in your customer portal at mylab.mybody-x.com.
How long does the analysis take?
\
DNA tests take 15 to 25 business days after the sample arrives, blood tests take 3 to 5 business days, and gut tests take 8 to 10 business days. Shipping the test kit to you happens beforehand and is listed separately, so you can plan for both parts of the process. Once your report is ready, you’ll receive an email and can download it as a PDF from the customer portal.
Our products are not intended to diagnose, treat, cure, or prevent diseases. DNA analysis is intended to provide nutrition and lifestyle guidance. It is not a diagnostic procedure, does not predict diseases, and does not replace a medical examination or consultation. Genetic variants describe probabilities in population groups, not determinations for individuals. Reference ranges depend on the laboratory, method, and age – the information on your report is always authoritative. The content is for general information and does not replace medical advice, diagnosis, or treatment.
