The tools for detecting false positives, false negatives, and interference in interactions when testing and monitoring therapeutic drug useFor physicians monitoring a patient's progress, efficacy of treatment is often linked to a patient's response to medication. Determining whether a patient is taking the prescribed amount, the drug or dosage is effective, or the prescribed medication is interacting with other drugs can be determined through drug testing. Written as a guide for toxicologists, chemists, and health professionals involved in patient care, Resolving Erroneous Reports in Toxicology and Therapeutic Drug Monitoring provides an up-to-date introduction to the tests and methodologies used in a toxicology lab as well as the sources of testing error that can lead to false positives, false negatives, and unreliable conclusions of drug abuse or under use.Covering a host of common therapeutic drugs as well as specific types of interference in immunoassays used in drug testing, the book details a number of possible testing scenarios and problems as well as solutions:False positive results in immunoassays for drugs in abuse testingInterferences in immunoassays used for monitoring anticonvulsants, tricyclic antidepressants, and digoxinFalse positive alcohol tests using breath analyzers and automated analyzersWhen a toxicology report is negative in a suspected overdose patient: the world of designer drugsEffects of drug-herb interactions on therapeutic drug monitoringPharmacogenomics and the general principles of genetic analysisApproaches for eliminating interference/discordant specimen in therapeutic drug monitoring and drugs in abuse testingWhat to do in case there is no readily available method for testingComplete with easy-to-read tables and flowcharts, this book helps toxicologists, clinical chemists, clinical pathologists, and forensic patholo
