title: Measuring drug levels in the office: rationale, possible advantages, and potential problems.
abstract: New technologies allow plasma levels of several drugs to be measured in the physician's office. Although such assays have the advantage of increased convenience for both physician and patient, they have a number of potential problems as well. Regardless of where plasma assays are performed, the physician must understand the rationale and pitfalls of therapeutic drug monitoring.
