The safety-code card is a pocket card that contains a quick overview of your PGx test results. Furthermore, the card contains a QR code that can be scanned by you or your healthcare provider with, e.g., a smartphone to quickly retrieve PGx-based dosing recommendations relevant to you. If you were assigned to the study group, your card is handed out to you by your local study team when your PGx test results are ready. Please take care of this card, and don’t forget to show it to your healthcare provider every time you receive a new prescription. If you were assigned to the standard of care group, you may receive your safety-code card once the study is finished.
