For 12 Years, Summit Diagnostics has Brought Stability to the Drug Testing Industry

Welcome to Summit Diagnostics. Twelve years ago, the Summit Diagnostics leadership team had a goal to create a company that truly understands the needs of medical professionals in the drug and alcohol testing industry.

Our vision was to help clients through the many pieces necessary to treat patients suffering from addiction.

Over those 12 years, Summit Diagnostics continues to see that vision through. We provide our clients with every tool necessary in their treatment of patients; Prescription monitoring, toxicology lab services, compliance services, and high quality drug testing devices.

With a strict emphasis on compliance, Summit has worked with thousands of clients to assure patient safety in their road to recovery, while helping to protect medical professional’s liability.
