Personalis is a contract research organization and genome-scale diagnostics services company pioneering genome guided medicine. We are focused on producing the most accurate genetic sequence data from each sample, and using our analytics and proprietary content to draw accurate and reliable biomedical interpretations of the data. Our tests are based on whole human genome and exome sequencing, conducted in our own laboratory. We utilize proprietary databases, advanced human reference sequences, and sophisticated algorithms to analyze results. We currently offer service for research use only, but aim to enter the clinical diagnostics market; our in-house laboratory is CLIA-licensed by the state board of California and CAP accreditation is in progress.
