This issue of Clinics in Laboratory Medicine, Guest Edited by Nigel Clarke, MD, and Andrew Hoofnagle, MD, will focus on Mass Spectrometry, with topics including: Proteins; Peptides; Small Molecules: Toxicology; Small Molecules: Diagnostics; and Regulatory Considerations.

Mass Spectrometry for the Clinical Laboratory is an accessible guide to mass spectrometry and the development, validation, and implementation of the most common assays seen in clinical labs. It provides readers with practical examples for assay development, and experimental design for validation to meet CLIA requirements, appropriate interference testing, measuring, validation of ion suppression/matrix effects, and quality control. These tools offer guidance on what type of instrumentation is optimal for each assay, what options are available, and the pros and cons of each. Readers will find a full set of tools that are either directly related to the assay they want to adopt or for an analogous assay they could use as an example. Written by expert users of the most common assays found in a clinical laboratory (clinical chemists, toxicologists, and clinical pathologists practicing mass spectrometry), the book lays out how experts in the field have chosen their mass spectrometers, purchased, installed, validated, and brought them on line for routine testing. The early chapters of the book covers what the practitioners have learned from years of experience, the challenges they have faced, and their recommendations on how to build and validate assays to avoid problems. These chapters also include recommendations for maintaining continuity of quality in testing. The later parts of the book focuses on specific types of assays (therapeutic drugs, Vitamin D, hormones, etc.). Each chapter in this section has been written by an expert practitioner of an assay that is currently running in his or her clinical lab. Provides readers with the keys to choosing, installing, and validating a mass spectrometry platform Offers tools to evaluate, validate, and troubleshoot the most common assays seen in clinical pathology labs Explains validation, ion suppression, interference testing, and quality control design to the detail that is required for implementation in the lab

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.
