Fig. 1. Current typical workflow of a clinical pharmacogenomics (PGx) test from ordering to reviewing.

First, a PGx test is ordered by the clinician. Second, the laboratory receives the physician’s order and sends a test kit to the patient to collect the patient’s DNA sample. The laboratory processes the patient’s sample after collection, and the raw genotyping data is processed. Third, the raw genotyping results are converted into a human-readable format and sent to the prescriber via electronic health records (EHR), email, or fax. Lastly, the results are shared with the patient by the physician.
