Clinical Toxicology Testing

Clinical toxicology in the laboratory sphere deals with the identification of chemicals, drugs, or toxins that may affect patients and offers a means for clinicians to predict future toxic effects, confirm a diagnosis, or optimize therapy. Drug testing can determine the presence or absence of drugs and/or drug metabolites and may be quantitative (particularly useful for therapeutic drug monitoring) or qualitative to verify compliance with prescribed therapy or identify inappropriate drug use (helpful in pain management). Pharmacogenetic (PGx) testing may be performed to help explain an adverse drug reaction or to help guide selection of drugs for an individual patient. Therapeutic drug management can help to optimize the dose of a therapeutic drug and is complementary to PGx testing.
