Detection and identification of prescription or over the counter drugs frequently found in drug overdose or used with a suicidal intent
This test is designed to qualitatively identify drugs present in the specimen; quantification of identified drugs, when available, may be performed upon client request
This test looks for a broad spectrum of prescription and over-the-counter (OTC) drugs. It is designed to detect drugs that have toxic effects, as well as known antidotes or active therapies that a clinician can initiate to treat 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. The test is not designed to screen for intermittent use or illicit drugs.
Drugs of toxic significance that are not detected by this test are: digoxin, lithium, and many drugs of abuse/illicit drugs, some benzodiazepines, and some opioids.
See Prescription and Over-the-Counter (OTC) Drug Screens in Special Instructions.
Drugs detected are presumptive. Additional testing may be required to confirm the presence of any drugs detected.
The drugs we know can be detected by this test are listed in Prescription and Over-the-Counter (OTC) Drug Screens in Special Instructions.
The pharmacology of each drug determines how the test should be interpreted. A detailed discussion of each drug is beyond the scope of this text. If you wish to have a report interpreted, call Mayo Medical Laboratories and ask for a toxicology consultant.
Mayo Medical Laboratories will only report reference ranges that we have determined to be clinically correlated. Other reference ranges are available from the literature, but since we have not validated them, we choose not to report them. We will gladly discuss them during a consultation and provide reference citations if requested.
Each report will indicate the drugs detected.
Not intended for therapeutic compliance testing.
Not intended for use in employment-related testing.
Not intended for drugs of abuse/illicit drug testing.
Not all drugs can be quantitatively extracted from the specimen, so accurate quantification may not be possible, and many do not have reference ranges.
For situations where chain of custody is required, a Chain-of-Custody Kit (T282) is available. See COCH / Chain-of-Custody-Processing.
