Emergency drug testing at Mayo Clinic is performed 24 hours a day, seven days a week in the Clinical and Forensic Toxicology Laboratory. Designed to manage apparent overdose or intoxicated patients, our emergency and overdose testing can help determine whether symptoms are due to the presence of drugs. Aimed at detecting drugs that have toxic effects but lack a known antidote or therapy, these evaluations are not appropriate for detecting drugs of abuse or to screen for intermittent or illicit drug use.

Prescription and over-the-counter (OTC) drug screens, which are performed using gas chromatography-mass spectroscopy (GS/MS), are available to test for a broad range of drugs in serum or urine. Drugs identified above reportable (detection) limits will be reported as present.
NOTE: Alcohol, LSD, digoxin, lithium, tetrahydrocannabinol (THC), some benzodiazepines, opiates, amphetamine-type stimulants, and most drugs of abuse are not detected by this testing. For these drugs, the specific confirmation tests should be ordered.
Quantitative serum toxicology testing is available to monitor toxicity in overdose cases.
