Genteract Whole Genome Sequencing looks at every position in your DNA and produces a comprehensive view of the entire genome. This is in contrast to Genotyping, which looks only at a vastly smaller set of positions (only about 600K Single Nucleotide Polymorphisms or SNPs), and to Whole Exome Sequencing, which looks at only about 1% of genome. Genteract Whole Genome Sequencing is a 1X sequencing which means that the entire genome is scanned once. The result of this is then analyzed using a process called Imputation, to get a comprehensive list of SNPs (over 60 Million SNPs). The results of this process have been shown to be more accurate than Genotyping (see here
for example) while being far more comprehensive.
