The Importance of Incorporating Drug-Drug Interactions and Lifestyle Factors in Pharmacogenomics-Guided Medication Management for Patients With Major Depressive Disorder in a Randomized Controlled Trial.

Sep 2023

In this study, drug-drug interactions accounted for 32% of all IDgenetix-guided drug recommendations, and lifestyle factors accounted for 11%. Incorporating these non-genetic factors in IDgenetix testing significantly impacts the number of drug recommendations and improves remission rates in patients with moderate to severe depression.

Asymmetrical pigmented lesion with high clinical suspicion for melanoma

Jun 2023

A 27-year-old female patient was seen by a primary care physician who recommended follow-up with a dermatologist for assessment of a concerning melanocytic lesion.

Multi-colored lesion with uncertain malignant potential

Jun 2023

Conflicting clinical and histopathological findings are resolved with the use of GEP test results.

Irregular papule with atypical histopathological findings and borderline/uncertain diagnosis

Jun 2023

Definitive diagnosis cannot be reached in an irregular, raised papule on the dorsal foot.
