Drug Monitoring, Antipsychotics, with Confirmation, Urine

Use

Therapeutic drug monitoring of antipsychotic medications via urine testing provides information on patient adherence, potential diversion, presence of non‑prescribed or illicit drugs, and unexpected variations in drug disposition, all of which can improve clinical decision‑making and patient management. Absence of an expected drug may indicate non‑adherence or diversion, while detection of a non‑prescribed or illicit drug may signal misuse; differences between expected and actual findings may also flag intolerance, drug interactions, or medical factors affecting elimination.
