Test Classification

This test was developed and its performance characteristics determined by Mayo Clinic in a manner consistent with CLIA requirements. It has not been cleared or approved by the US Food and Drug Administration.

Clinical Information

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.
