How Genetic Tests Work
What are Genetic Test Kits?
Fenix Genetic Test Kits are simple at-home cheek swab tests that analyze key genes involved in brain health, cognition, methylation, and nutrient metabolism. While your genes don’t determine your future, they can reveal helpful tendencies and blind spots, allowing you to make more informed, personalized health choices.
Powered by GeneMetrics, your results are delivered in easy-to-understand reports with practical suggestions, designed to provide usable, science-backed insights.

Frequently Asked Questions
-
Your results are generated through GeneMetrics’ laboratory, which is CLIA- and CAP-certified—two of the highest standards for clinical lab quality and accuracy. The testing and reporting process is backed by a multidisciplinary team spanning genetics, molecular biology, bioinformatics, clinical research, and medical data science. Just as importantly, the interpretation system is continuously refined using current, peer-reviewed scientific research and validated sources. The end goal is to provide results that are both technically reliable and translated into clear, evidence-based insights you can actually use in clinical and wellness decisions.
-
Yes, your genetic information is used only to run your test and generate your personal results—it is not sold, shared for advertising, or used for unrelated research. Testing is processed by GeneMetrics, a clinical laboratory partner that operates under HIPAA and GDPR privacy standards. Your data is protected using multi-level encryption, and GeneMetrics uses data separation (your personal details are stored separately from your genetic data) to reduce risk even further. Genetic information is stored in an anonymized genome database, meaning it is not kept in a way that directly identifies you. Results are shared only with you (and your provider if you request it).
-
No. The reports are designed to be easy to understand, but they are also practitioner-friendly if you choose to share the results with your doctor.
-
Yes. You can unlock additional genetic reports anytime using the same test kit. No need to swab twice, just unlock the additional reports after your results are in.
