The science

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.

Coverage

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.

MethodHow much of your genomeWhat it can tell you
SNP array (most DNA kits)About 0.1%, a fixed list of spotsOnly the variants the chip checks
Whole-exomeAbout 1 to 2%, coding regions onlyProtein-coding genes only
Meridian 30x WGS100%, your whole genomeThe complete picture, re-usable for life

Coverage figures are approximate and illustrate typical methods. 30x is average sequencing depth.

Sequence once

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.

Private by design

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.
