What this test is

Drug testing is a laboratory analysis that screens for common drugs of abuse, prescription medications, or other substances in the body. It can be performed on blood or urine, depending on the test ordered. The results provide information about recent or past drug use.

What it measures

  • Amphetamines — Detects stimulant drugs like methamphetamine or prescription amphetamines.
  • Barbiturates — Detects sedative drugs that depress the central nervous system.
  • Benzodiazepines — Detects anti-anxiety medications such as diazepam or alprazolam.
  • Cannabinoids — Detects marijuana use by identifying THC metabolites.
  • Cocaine — Detects cocaine use by identifying its metabolites.
  • Opiates — Detects natural or synthetic opioids like heroin, morphine, or codeine.
  • Phencyclidine — Detects the hallucinogen PCP.

What the test involves

For a blood drug test, a healthcare professional collects a blood sample from a vein in your arm using a needle. For a urine drug test, you provide a urine sample in a private collection area, following the lab's instructions.

Why it is often ordered

A clinician may order drug testing to screen for substance use as part of a medical evaluation, to monitor compliance with a treatment plan, or for employment or legal purposes. It can also help diagnose a drug overdose or poisoning.

Preparation

Preparation instructions vary depending on the specific test and the lab performing it. Always follow the collection lab's instructions carefully, as some tests may require fasting or avoiding certain substances beforehand.

How results are reported

Results are typically reported as positive or negative for each substance tested, and sometimes with a quantitative level. Reference ranges and cutoff values vary by laboratory, so results should be interpreted in the context of the lab's own standards.
