Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Clinical Applications of Mass Spectrometry in Drug Analysis written by Uttam Garg and published by Springer Nature. This book was released on 2023-11-30 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully updated volume describes methods and protocols for a number of drugs and toxins in a stepwise manner. Exploring the versatility and flexibility of mass spectrometry, the book covers the advantages of this technology, which typically include elimination of the need for special reagents such as antibodies, increased sensitivity and specificity, and multi-component analysis enabling the screening of tens to hundreds of compounds in a single assay run. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Clinical Applications of Mass Spectrometry in Drug Analysis: Methods and Protocols, Second Edition serves as a valuable resource for laboratory professionals who are already utilizing mass spectrometry or considering bringing this technology to their labs.
Download or read book Method Development and Validation for Drug Identification and Confirmation by LC MS MS for Limited specimen Cases written by Danielle E. Ross-Carr and published by . This book was released on 2017 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Driving under the influence of drugs (DUID) cases represent the largest portion of cases handled in most forensic toxicology laboratories. Blood is a commonly used specimen and is often analyzed using gas chromatography-mass spectrometry (GC/MS). A common extraction for this method requires two milliliters of blood. If more than one extraction is necessary, a larger volume of blood is required. Recently, laboratories have started using liquid chromatography-mass spectrometry (LC/MS) to obtain a lower limit of detection and extractions which require less blood to complete. Currently, the Oklahoma State Bureau of Investigation (OSBI) Laboratory operates LC-based extractions which require 250 to 500 microliters (μL) of sample to complete, but these are limited to specific drug classes. A general drug screen for forty drugs has been developed and validated using 250 microliters of blood. Even with this reduction of volume requirements, there are still instances in which less than one milliliter (mL) of blood is available for use by the analyst. An additional validation has been completed which required 100 microliters of sample to confirm the presence of thirty-nine drugs. A comparison between these methods was completed to verify the sensitivity of the 100 microliter method.

Available in PDF, EPUB and Kindle. Book excerpt: This book enables the reader to gain a rapid understanding of GC/MS analysis through a basic knowledge of the fundamental principles, linking these with simple and practical applications in the field of industrial medicine and analysis of drugs. Additional information from other specialist fields is also provided with the aim of helping the analyst to understand their relevance to the interpretation of results. The book describes efficient methods of sample preparation and quality assurance and provides information on epidemiology and pharmacology, without which drug screening is impossible. This comprehensive overview is mainly written for the practical analyst in the clinical laboratory but it is equally suited for teaching purposes.

Download or read book Field deployable Gas Chromatography mass Spectrometry GC MS Analysis of Illicit Drugs written by Leah Rynearson and published by . This book was released on 2019 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: False positive results from on-scene illicit drug analysis using presumptive color tests have caused numerous wrongful arrests (Lieblein 2018). In many states, forensic laboratories do not ever receive the sample for confirmative identification unless the defendant goes to trial, which makes it impossible to know the severity of this problem. Additionally, some defendants take a plea deal, which can result in these defendants spending months or years in prison for a crime they did not commit. Improving the reliability of on-scene illicit drug testing by incorporating confirmatory methods capable of achieving very low limits of detection such as gas chromatography-mass spectrometry (GC-MS) into the field could help reduce these wrongful arrests. The purpose of this research was to build a spectral library of illicit drugs and additive spectra for a commercially available portable ion-trap GC-MS, the Torion T-9 from Perkin-Elmer. Due to the potential for space charge and ion-ion interactions in ion trap mass spectrometers, the resulting MS spectra produced can be different than standard quadrupole MS. Thus, a customized library for this type of field application is critical. Over fifty (50) illicit drugs and fifteen (15) additives were used to create a GC-MS library after repeated testing. This customized GC-MS library was then used to test the ability to detect and identify illicit substances and their additives in seized drug samples, provided by the Connecticut State Police K9 Unit, which had not undergone laboratory testing. In addition, results were compared with data generated from the same samples using a field-portable quadrupole GC-MS. Of the twelve (12) samples tested, a positive identification for a controlled substance was made for ten (10) of them, using spectral data in the customized GC-MS library. The other two (2) contained unknown peaks that were not identified by any available GC-MS or MS library. Future studies should work on refining the retention time for each drug, performing tests with different versions of the Torion T-9 to ensure robustness of the GC-MS library, and continuous addition of illicit drug and additive standards to further expand the GC-MS library.
