Read the whole book, not a few pages.
Your genome is about three billion base pairs. Most consumer DNA kits read a tiny, pre-chosen fraction of it. Whole-genome sequencing reads essentially all of it, deeply enough to trust, once.
Why 30x, and why the whole genome.
“30x” means each position in your genome is read about thirty times on average. That redundancy is what makes a read reliable rather than a guess. And because whole-genome sequencing covers the entire genome, not a fixed list of spots, the same data can be re-read for new findings for the rest of your life.
| Method | How much of your genome | What it can tell you |
|---|---|---|
| SNP array (most DNA kits) | About 0.1%, a fixed list of spots | Only the variants the chip checks |
| Whole-exome | About 1 to 2%, coding regions only | Protein-coding genes only |
| Meridian 30x WGS | 100%, your whole genome | The complete picture, re-usable for life |
Coverage figures are approximate and illustrate typical methods. 30x is average sequencing depth.
Your genome does not change. So you only read it once.
Written at birth and unchanged for life, your genome is the one dataset that never expires. Sequence it a single time and every new discovery becomes something you can learn from data you already own. We re-read it as genomic science grows, with no new sample needed.
Read on your device, not on our servers.
Your genome is stored encrypted with a key only you hold. When you explore it, the work happens on your own device. We delete our copy once you have downloaded your file, and our laboratory partners destroy your biological sample within 30 days of delivery.
