Useful For
Suggests clinical disorders or settings where the test may be helpful

Qualitative detection and identification of prescription or over-the-counter drugs frequently found in drug overdose or used with a suicidal intent

 

Providing, when possible, the identification of all drugs in the specimen

 

This test is not intended for use in employment-related testing.

 

This test is not intended for therapeutic compliance testing. The assay's limits of detection have been established for drugs at overdose levels, which are generally much higher than therapeutic concentrations.

 

This test is not useful for drugs of abuse or illicit drug testing, including benzodiazepines, opioids, barbiturates, cocaine, and amphetamine type stimulants.

Providing, when possible, the identification of all drugs in the specimen

 

This test is not intended for use in employment-related testing.

 

This test is not intended for therapeutic compliance testing. The assay's limits of detection have been established for drugs at overdose levels, which are generally much higher than therapeutic concentrations.

 

This test is not useful for drugs of abuse or illicit drug testing, including benzodiazepines, opioids, barbiturates, cocaine, and amphetamine type stimulants.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

This test looks for a broad spectrum of prescription and over-the-counter medications. It is designed to detect drugs that have toxic effects, as well as known antidotes or active therapies that a clinician can initiate to counteract the toxic effect. The test is intended to help physicians manage an apparent overdose or intoxicated patient or to determine if a specific set of symptoms might be due to the presence of drugs. This test is not appropriate for drugs of abuse or illicit drug testing, including benzodiazepines, opioids, barbiturates, cocaine, and amphetamine-type stimulants.

 

Drugs of toxic significance that are not detected by this test are digoxin, lithium, salicylate, and many drugs of abuse or illicit drugs, some benzodiazepines, and some opioids. For these drugs, see Mayo Clinic Laboratories' drug abuse surveys, drug screens, or individual tests.

 

For detection limits for drugs detected in this test see Prescription and Over-the-Counter Drug Screening List and Limits of Detection.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Drugs detected are presumptive. Additional testing may be required to confirm the presence of any drugs detected.

Interpretation
Provides information to assist in interpretation of the test results

The drugs that are detected by this test are listed in Prescription and Over-the-Counter Drug Screening List and Limits of Detection.

 

A detailed discussion of each drug detected is beyond the scope of this text. Each report will indicate the drugs identified. If a clinical interpretation is required, contact Mayo Clinic Laboratories at 800-533-1710 and ask to speak to a toxicology consultant.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

No significant cautionary statements
