Propoxyphene 75 ng/mL 3. Drugs/Drug classes reported as "Positive" are
automatically reflexed to mass spectrometry
confirmation/quantitation testing. An immunoassay
unconfirmed positive screen result may be useful for medical
purposes but does not meet forensic standards. 4. The
absence of expected drug(s) and/or drug metabolite(s) may
indicate non-compliance, inappropriate timing of specimen
collection relative to drug administration, poor drug
absorption, or limitations of testing. The concentration at
which the screening test can detect a drug or metabolite
varies within a drug class. Specimens for which drugs or drug
classes are detected by the screen are automatically reflexed
to a second, more specific technology (mass spectrometry).
The concentration value must be greater than or equal to the
cutoff to be reported as positive. Interpretive questions should
be directed to the laboratory. 5. For medical purposes only;
not valid for forensic use. Test Performed by: ARUP

Drug Screen, Prescription/OTC, Gastric
Clinical Information: 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, to determine if a specific set of symptoms might be
due to the presence of drugs, or to evaluate a patient who might be abusing these drugs intermittently. The
test is not designed to screen for intermittent use of 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 opiates.
Useful For: 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 provide, when possible, the
identification of all drugs present.
Interpretation: The drugs that can be detected by this test are listed in Prescription and
Over-the-Counter (OTC) Drug Screens Table 2 in Special Instructions. Positive results are definitive.
Drugs of toxic significance that are not detected by this test include digoxin, lithium, many drugs of
abuse/illicit drugs, some benzodiazepines, and some opiates. For these drugs, see Mayo Medical
Laboratories' drug abuse surveys or drug screens or individual tests. 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, please request a Drug/Toxicology Lab consult (Mayo Clinic patients) or contact
Mayo Laboratory Inquiry (Mayo Medical Laboratories clients).
