Resolving Erroneous Reports in Toxicology and Therapeutic Drug Monitoring. A Comprehensive Guide

The tools for detecting false positives, false negatives, and interference in interactions when testing and monitoring therapeutic drug use

For 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 testing
- Interferences in immunoassays READ MORE >
