Who We Help


Drug addiction is a complex disorder with many variables. A physician who provides any kind of addiction treatment faces obvious questions. Am I doing the right thing for my patients? Are my patients doing the right thing for themselves?

Recovery requires honesty. It is up to the clinician to help his/her patients. A comprehensive drug-testing program has become an integral component of patient care.

Comprehensive drug monitoring can be an integral component to patient care. Rely on our laboratory testing services to determine if patients are abusing or complying with their treatment program. Our LC-MS/MS instrumentation and automated processes provide you fast, accurate and quantitative results.

Pharmacogenomics testing is extremely helpful to doctors working in addiction treatment. It allows them to understand how patients may metabolize prescription drugs and whether the treatment will be successful. In addition, our toxicology lab services can detect even the tiniest amounts of common and not-so-common drugs.

Our extensive test menu of more than 85 drugs and metabolites is updated as soon as new drugs emerge. This commitment to constantly stay cutting-edge, along with our state-of-the-art facility that meets all COLA and applicable federal and state laws, rules and regulations, helps you provide your patients with the highest level of care and attention.
