New Study Shows that the Drug-Drug Interactions and Lifestyle Factors Provided by Castle Biosciences’ IDgenetix Test Significantly Improve Medication Recommendations Over Drug-Gene Interactions Alone for Patients 65 and Older - Seite 2

All patients in the study had genetic polymorphisms that could impact medication selection in at least three of the 15 genes on the IDgenetix report. While drug-gene interactions accounted for 66% of all medication recommendations, drug-drug interactions and lifestyle factors accounted for 34% (27% and 7%, respectively), demonstrating the value of the IDgenetix 3-in-1 test in providing tailored guidance to help clinicians select the optimal medications for their patients.

About IDgenetix

IDgenetix is a pharmacogenomic (PGx) test for depression, anxiety and other mental health conditions designed to analyze a patient’s genetic make-up to guide timely and evidence-based decisions on the optimal drug for each patient. IDgenetix is designed to provide important genetic information to clinicians to help guide personalized treatment plans for their patients, with the potential to help patients achieve a faster therapeutic response and improve their chances of remission by identifying appropriate medications more efficiently than the standard of care trial-and-error approach. IDgenetix provides drug-drug and drug-gene interactions and is supported by a published, peer-reviewed randomized controlled trial that demonstrated clinical utility over the standard of care when physicians used IDgenetix prior to prescribing a medication. IDgenetix is currently reimbursed by Medicare for the following eight mental health conditions: major depressive disorder, schizophrenia, bipolar disorder, anxiety disorders, panic disorder, obsessive-compulsive personality disorder, post-traumatic stress disorder and attention deficit hyperactivity disorder.
