How do you test for toxic?

Whole blood, serum, or plasma specimens are typically preferred for most testing; quantitative results can be used to assess signs and symptoms of toxicity. Urine can be used to assess acute or chronic exposure within an average window of detection of 1-3 days.

Emergency toxicology focuses on the diagnosis, management, and prevention of poisoning due to drugs, occupational and environmental toxins, and biological agents. Examples of exposures include acute drug overdoses, hazardous exposure to chemical products, and the management of drug withdrawal syndromes. Toxicology test results are useful not only to determine patient exposure and assess symptoms of toxicity, but also for serial monitoring to evaluate treatment efficacy and determine if toxin concentrations have decreased over time. Test results should be interpreted based on the established therapeutic or toxic range (if applicable), timing of specimen collection relative to the time of exposure, specimen type, and the patient’s clinical signs and symptoms of toxicity. Concomitant medications and factors relevant to the window of detection will also affect the interpretation of results (see Frequently Asked Questions ). Note that adverse drug responses can occur even when drug concentrations are within the therapeutic range. Whole blood, serum, or plasma specimens are typically preferred for most testing; quantitative results can be used to assess signs and symptoms of toxicity. Urine can be used to assess acute or chronic exposure within an average window of detection of 1-3 days. In emergency situations, there are no specific timing recommendations; instead, specimens should be collected as soon as possible.

Indications for Testing

Testing for toxicity may be indicated in the following situations:

Accidental or intentional poisoning from illicit or licit substances

Decontamination or detoxification

Suspected overdose of licit or illicit substances in a patient presenting with altered cognition

Metabolic acidosis of unknown cause

Signs and symptoms of toxicity in the event of a known or suspected hazardous exposure

Timing of Specimen Collection

In an acute emergency, specimens should be collected as soon as possible if toxicity is suspected. If assessing decontamination or detoxification (eg, in the case of acetaminophen poisoning), retest intervals are determined on a case-by-case basis.

Specimen Selection

Whole blood, serum, or plasma is preferred for most testing because these specimens can provide both 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 required 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 an individual 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, plasma, and urine specimens?

In general, the window of detection in blood, serum, and plasma is 1-2 days after drug administration. Urine specimens typically have an average window of detection of 1-3 days. 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, solubility, stability)

Patient age

Patient body composition and sex

Patient pathophysiology and pharmacokinetics

Coadministration of other medications

Hydration and nutrition status

Analytical limitations of testing

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, which may cause a falsely low result.

Why do people feel unhappy in a relationship?

People reach this point for a range of reasons. Maybe you feel like you’ve become different people since getting together. There’s nothing wrong with that: people change. It can be hard though, for a relationship to keep up with the change - especially if you haven’t had a chance to talk about what’s happening. Maybe you feel like you aren’t spending enough time together, or that when you do, it’s just not relaxed or fun. Or maybe you’re just not sure. Maybe you can’t figure it out - all you know is that you used to like being in this relationship, and now you don’t know.
