      These cut‐offs specify the minimum concentration of a drug or metabolite that constitutes a positive test. All concentrations are in ng/mL. Samples with a positive initial test must undergo a confirmatory test before reporting the result. Grouped analytes such as codeine/morphine are both detected in the initial test, but they are measured and reported separately in the confirmatory test.

      This book was written for students and practitioners who want a concise description of drugs of abuse and how clinical laboratories test for them. The emphasis is on interpretation of test results rather than analytical methods. The first section covers basic concepts of drug metabolism, specimen collection, and techniques for detecting and measuring drugs. The following section contains chapters on individual drugs or drug groups, all organized under similar headings. Practical information about laboratory tests (i.e., screening cut‐offs, length of time a drug can be detected, interferences) is included. Lists of metabolites that indicate use of a particular drug are provided in Appendix A.

      A number of case studies are attached to each chapter on individual drugs and drug groups. They are meant to pose real‐world situations in which the facts and principles discussed in this book can be applied. Cases are drawn from most of the areas mentioned above – emergency medicine, addiction medicine, pain management, workplace testing, and forensics.

      Drugs of abuse testing sits at the crossroads of analytical chemistry, pharmacology, toxicology, and several branches of medical practice. When searching for information about a particular drug or topic, you may need to consult a variety of sources. The following general references are recommended as a starting point.

      Textbooks

      1 Katzung, B.G., Masters, S.B., and Trevor, A.J. (eds.) (2012). Basic and Clinical Pharmacology, 12e. New York: McGraw‐Hill.

       A classic in the field. Chapters are well organized, well written, and well illustrated. This text is worth reading to learn the basics or fill in knowledge gaps.

      1 Baselt, R.C. (2011). Disposition of Toxic Drugs and Chemicals in Man, 9e. Seal Beach, CA: Biomedical Publications.

       This book presents curated information on more than 1000 drugs and chemicals. Each entry contains sections on occurrence and usage, blood concentrations, metabolism and excretion, toxicity, and analysis. It is an essential reference for toxicology laboratories.

      1 Hoffman, R.S., Howland, M.A., Lewin, N.A. et al. (eds.) (2015). Goldfrank's Toxicologic Emergencies, 10e. New York: McGraw‐Hill.

       Another classic, Goldfrank's is the reigning bible of toxicology in the emergency setting. Historical background, pharmacology, pathophysiology, clinical presentation, diagnosis, and management are covered for most drugs/toxins/poisons. Chapters are somewhat variable in structure and content.
