This is a whole-genome-sequencing of good accuracy. Most commercialized DNA tests, like 23andme, measure "SNIPs": specific letters of the DNA; whole genome sequencing measures almost all letters. Most commercialized DNA tests are of precision "1x", a good precision would be "50X", as it averages the result over 50 measures of DNA (each having noise, notably DNA mutations during the preparation process). This test is "30X", with relatively few errors.
