DNA testing is like getting a personalized blueprint of your body by examining your genetic code—deoxyribonucleic acid (DNA), which is the instruction manual made up of about 3 billion chemical "letters" (bases) that determines traits like eye color, disease risks, and how you respond to medications. These tests scan specific parts of your DNA to spot patterns or variations (called single nucleotide polymorphisms, or SNPs—pronounced "snips"—which are tiny differences in your genetic letters) that might influence your health, nutrition, or fitness.

Not all DNA tests are the same. Some companies, called providers, focus on ancestry, revealing where your family originated from centuries ago by matching your DNA to global populations. Others zero in on health, checking for risks of conditions like heart disease or cancer, or how your body might process vitamins, caffeine, or drugs differently. Imagine DNA as a vast library of books—ancestry tests might read the table of contents for family history, while health tests dive into chapters on wellness and risks. No single test reads the entire library; they each cover different sections based on what the company prioritizes.

This is where gaps can appear: An ancestry test might miss health details, leaving you with an incomplete picture. That's okay—providers often let you download your raw data (the unprocessed genetic info) to share elsewhere. OneVital steps in to bridge these gaps. We take your DNA data from any major provider, combine it with info from your wearables (like sleep trackers or fitness bands that measure heart rate variability, or HRV—a quick recovery sign after stress) and lab blood tests, and provide clear, actionable insights. It's like assembling puzzle pieces from different boxes into one complete image of your health.
