23andMe is a DNA analysis service providing information and tools for individuals to learn about and explore their DNA.
We use the Illumina HumanOmniExpress-24 format chip (shown here). Our chip consists of a fully custom panel of probes for detecting single nucleotide polymorphisms (SNPs) selected by our researchers. The selection was made to maximize the number of ancestry features available to customers as well as offer flexibility for future research.
All of the laboratory testing for 23andMe is done in a CLIA-certified laboratory. ($99)
