PtProtect® – Toxicology Experts Are Just a Phone Call Away

PeaceHealth Laboratories has long been respected for its proficiency in drug testing. Sharing this expertise through clinical and technical consultation is a hallmark of PeaceHealth Laboratories values. Board-certified toxicology experts Grant Beardsley and Stephen Erfurth consider it a privilege to answer questions that help physicians make the right decisions for their patients. They are passionate about the work they do and welcome your calls.

Grant Beardsley, MS

It is not uncommon to find PeaceHealth Laboratories’ clinical toxicologist Grant Beardsley responding to questions such as, “Why am I getting a negative opiate screen result when this patient is taking methadone?” or “How long does it take to produce a negative test result after the last dose of a narcotic analgesic?” Physicians and their assistants find his personal responses both thorough and educational.

As a 32-year PeaceHealth Laboratories veteran, Grant is as familiar with pharmacology of opiates and opioids as he is with laboratory techniques enlisted to detect drugs critical to any medication safety program.

“Being available to consult with physicians and others on their questions is an integral part of our service.”

Grant has appeared as an expert witness in more than 50 drug testing trials, and is a sought-after speaker by associations and universities. Grant holds a Master of Science in Pharmacology/Toxicology from the College of Pharmacy at Oregon State University in Corvallis, OR. He is certified as both a clinical chemist and a toxicological chemist by the National Registry in Clinical Chemistry.

Stephen Erfurth, PhD

As PeaceHealth Laboratories’ Director for Science and Technology, Stephen Erfurth, PhD, is our resident strategist when it comes to the future of laboratory medicine.

Dr. Erfurth was the first to note that physicians needed more definitive testing to prescribe and monitor patient adherence with confidence. He began developing PtProtect as a powerful tool to assist physicians in limiting diversion, detecting abuse and preventing overdoses.

Dr. Erfurth works closely with Grant Beardsley and his team in developing new proprietary assays for PeaceHealth Laboratories’ medication safety program.

“Toxicology, chemistry and molecular diagnostics will be merging as clinicians look to the laboratory to help with medication safety issues.”

Stephen Erfurth holds a PhD in Chemistry from the University of Oregon and was a post-doctoral resident in Clinical Pathology/Clinical Chemistry at University of Oregon Health Sciences Center. He is a Diplomat of the American Board of Clinical Chemistry (DABCC) in two specialties: Toxicology and Clinical Chemistry.
