Companion Diagnostics

Companion Diagnostics, often operating as CompanionDx, was a specialized diagnostic company focused on pharmacogenomics and personalized medicine. The company provided high-complexity laboratory testing services designed to help clinicians determine the most effective medications and dosages for patients based on their genetic profiles. Their primary offerings included tests for drug metabolism, oncology treatment response, and pain management optimization. By integrating genetic data with clinical decision support, the company aimed to reduce adverse drug reactions and improve therapeutic outcomes. In 2015, the company's assets and laboratory operations were largely integrated into or acquired by other entities following financial restructuring.
