Find relatives across 2,000+ regions. Compare microarray accuracy, database sizes, and ethnicity breakdowns from AncestryDNA, MyHeritage, and more.
Get the most accurate DNA test available (100% of your genome). Track your real biological age. Your DNA isn't just history—it's your blueprint for living longer and healthier.
Not all DNA tests are created equal. They fall into two camps, and knowing the difference will save you time and money.
Which type of DNA test do I need?
Want to find relatives or explore your ancestry? Get a Heritage Test (Ancestry, MyHeritage, or Living DNA). They compare your DNA to millions of others.
Want health insights, diet guidance, or biological age? Get a Health & Longevity Test (SelfDecode, Dante Labs, or Sequencing.com). Some read 100% of your DNA.
These tests compare your DNA to millions of other people to find long-lost cousins or pin down exactly which village your ancestors came from.

Clear answers to the most common questions about DNA testing, technology, and privacy.
It depends on your goal:
Yes — and this is the smartest strategy. Buy one test, then upload the raw data to other platforms:
This lets you get multiple perspectives from a single spit sample.
WGS provides 9,000x more data.
Microarray (23andMe, Ancestry): ~700,000 SNPs (0.02% of genome)
Whole Genome Sequencing: 6.4 billion base pairs (100% of genome)
For rare variant detection and comprehensive longevity analysis, WGS is the superior choice. For ancestry matching with large databases, microarrays remain useful.

Q30 means a 1-in-1000 chance of error per base call. Dante Labs guarantees ≥90% Q30 on their NovaSeq X platform. Sequencing.com guarantees ≥85%. Always verify Q30 metrics before purchasing WGS services.
Compare WGS providers95%+ accuracy for common variants (MAF >5%) in Europeans. Lower accuracy for rare variants (<1% MAF) and non-European ancestry.
SelfDecode imputes ~83 million variants from 700k SNP input. Useful for polygenic risk scores, but not for clinical rare variant analysis. When accuracy matters for specific rare variants, real WGS is required.
How imputation worksIt depends on the company:
