This issue of Clinics in Laboratory Medicine, edited by Dr. Martin Bluth, will cover a wide array of topics related to drug testing and toxicology. Experts will discuss common drugs in analgesia, toxicology techniques, errors and interferences in toxicology testing, toxicology considerations in pain and addiction medicine, toxicology in reproductive endocrinology, forensic toxicology, and toxicology in emergency medicine, among others.

This issue of Clinics in Laboratory Medicine, titled Toxicology Testing, includes the following topics; Progress in Clinical Toxicology Testing, The Prescription Drug Abuse Epidemic, Substance Abuse Among Healthcare Professionals, Pain Management Drug Testing, Ethanol Biomarkers, Newly-emerging Drugs of Abuse, Synthetic Cannabinoids, Synthetic Cathenones, Immunoassay Methodology in Drugs-of-abuse Testing, Toxicology Testing in Alternative Specimen Matrices, Principles and Procedures in Postmortem Toxicology, and Pharmacogenetics and the Future of Toxicology Testing. Advances in toxicology testing are paving the way for major improvements in the way scientists evaluate health risks posed by toxic chemicals. Toxicity tests help scientists better understand how the human body carries out normal functions that are key to maintaining health. Therefore, this topic is important to the field of Laboratory Medicine.
