Prescription Monitoring
Therapeutic Drug Monitoring

Therapeutic drug monitoring (TDM) is the use of drug concentration measurements in body fluids as an aid to the management of drug therapy for the cure, alleviation or prevention of a disease.
In the era of Pharmacogenomics, TDM testing is valuable in adjusting the dosage of drugs according to the characteristics of the patient and the response obtained.
TDM is applied to ensure patient compliance with a therapy regimen or to detect occurrences of addiction or abuse.

Urine Toxicology Screen
Toxicology Drug Screen

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

Drug Confirmation Testing
Drug Confirmation Testing

Presumed positive results identifying a class of drugs are further tested by specialized confirmatory methods. Confirmatory tests use multiple parameters to positively quantitate a drug with levels of detection ranging in the sub ng/ml range.
Some drug abuse can only be measured via LC/MS-MS to identify and quantify psychoactive substances entering the market (fentanyl derivatives, for example).
