"The urine drug screen commonly utilized in the emergency department is an immunoassay that uses antibodies to detect specific drugs or their metabolites. This allows for rapid screening for drugs of abuse, but it has many limitations.
Gas chromatography-mass spectrometry (GC-MS) is the confirmatory test, but it is more costly, time-consuming, and generally can only be performed by outside laboratories. This confirmatory test is generally not useful in the emergency department, but has a role in cases of pediatric exposures, research, or occupational drug testing...
Urine drug screens can be thought of as the good, the bad, and the ugly. Screens that are positive for cocaine, THC, or barbiturates are usually true-positives. Screens that are negative for benzodiazepines or opiates could be false-negatives. Depending on the clinical scenario, urine drug screens positive for TCAs, amphetamines, or PCP are more likely to be a false-positive than a true-positive."
