Drug Screening

Companies, government agencies and insurance organizations frequently require a laboratory test for illegal drugs and alcohol. The screening almost always includes collecting a urine specimen. This is especially true since most substances being tested for stay in the urine even after a person's intoxication or impairment has passed.

A serum (blood) test is generally reserved for when you have "real time" impairment or right after ingestion of a prohibited substance. In addition, some organizations require the entire testing process to follow a stringent chain of custody.

Urine Screening

A normal drug screening consists of collecting a urine specimen. The following is a list of the most widely performed drug and alcohol screening tests:

• Amphetamines (Methamphetamines)
• Barbiturates
  
  • Phenobarbitol
  • Secobarbital
• Benzodiazapines (Valium class drugs)
• Cocaine / Cocaine Metabolites
• Opiates / Heroin Morphine
• Methadone
• Phenycyclidine (PCP)
• Propoxyphene Metabolites
• Tetrahydrocannabinol (THC)

False-positives and false-negatives

An amphetamine test may produce a false-positive result if you're taking medications that have phenylpropanolamine or pseudoephedrine. Also, a false-positive opiate test may result from eating poppy seeds (confirmation testing usually resolves this issue). In addition, urine "over dilution" and other factors can cause a false-negative result.
