Clinical Significance
Toxicology screens are used to identify substances
affecting a patient and to guide the clinician to predict
future toxic effects, to confirm the differential
diagnosis or to guide therapy. Accurate diagnosis of
clinical intoxication secondary to illicit drug use based
on clinical history and physical examination may be
difficult without laboratory confirmation. This testing
is also necessary when multiple drug ingestion is
involved, as the effects of one drug may mask the
clinical signs and symptoms of the effects of other drugs.
