Does 23andMe, Ancestry.com & MyHeritage test my entire genome?
No, their DNA tests do not sequence your genome.
The type of testing technology used by 23andMe, Ancestry.com, and similar companies test less than 0.1% of your genome. Their tests, which are called genotyping microarray tests, do not sequence your genes and do not test your whole genome.
Only a special type of genetic testing called DNA sequencing has the ability to test your entire genome. Our Ultimate Genome Sequencing service, which includes clinical-grade whole genome sequencing, tests 100% of your genome.
