excellence in drug abuse testing

Customer Service

Our philosophy is to provide Customer Service Professionals who answer all inquiries in a timely, accurate, and friendly manner. Clients may call toll-free with questions regarding general interpretation of test results, specimen collection and handling requirements, and specimen transportation issues. If our Client Services Department does not know the answer to your question, they will refer you to the appropriate staff member. Our mission is to develop a professional relationship with our clients to ensure they are satisfied.

Customer Service staff is available to serve you, including:


Urine collections are available on our premises or in pre-arranged onsite destinations. Friends Lab will also arrange for out of state collections with our list of referral collection sites.

Expert Drug Information

Consultation regarding interpreation and utilization of drug test results is readily available from our Toxicologists. They can provide important insight on drug testing issues and address any legal concerns. What substances interfere with certain assays? How does one tell if a specimen has been contaminated? Does a positive result indicate recent abuse or remnants of abuse? Laboratory test results can sometimes be very confusing, especially to the novice. Our staff is experienced in answering these scientific questions. Commonly asked questions are also answered in our Drug Information library online.
