Emergency Toxicology

Emergency toxicology focuses on the diagnosis, management, and prevention of poisonings due to drugs, occupational and environmental toxins, and biological agents. Examples of exposures include acute drug overdoses, hazardous exposures to chemical products, and the management of drug withdrawal syndromes.

Tabs Content

Clinical Overview

Indications for Testing

Accidental or intentional poisoning from illicit or licit substances
Decontamination or detoxification
Suspected overdose of licit or illicit substances in patient presenting with altered cognition
Metabolic acidosis of unknown cause
Signs and symptoms of toxicity in event of known or suspected hazardous exposure

Timing of Specimen Collection

In acute emergency, there are no specific timing recommendations – specimens should be collected as soon as possible if toxicity is suspected
For decontamination or detoxification samples (eg, Tylenol poisoning) – intervals for retesting are determined on a case by case basis

Specimen Selection

Serum – used for most testing; provides quantitative and qualitative information
Urine – may be used in select cases when only qualitative information is needed

Frequently Asked Questions

What is the definition of half-life?

The half-life of a drug refers to the time it takes for 50% of the drug to be eliminated from blood.

What is the definition of steady-state concentration?

Steady-state concentration occurs when the rate of drug administration is equal to the rate of elimination. Generally, steady-state concentration can be achieved after patient has consistently administered the drug for the duration of 5-7 half-lives (eg, if a drug has a half-life of 24 hours and is administered once a day, then steady-state concentration can be achieved after 5-7 days of drug administration).

What is the window of detection of drugs in blood, serum, or plasma specimens?

In general, the window of detection in blood, serum, and plasma is 1-2 days after drug administration.

The window of detection for drugs is dependent on several factors, including the following

Half-life of the drug
Drug dose
Frequency of drug administration
Route of administration
Drug formulation
Chemistry of the drug (eg, water soluble vs lipid soluble)
Patient’s age
Patient’s body composition and sex
Patient’s pathophysiology and pharmacokinetics
Coadministration of other medications
Hydration and nutrition status

Can gel separator tubes be used for toxicology testing?

Gel separator tubes are not recommended for testing in toxicology. Drugs that are lipid soluble may be absorbed into the gel and may cause a falsely low drug result.
