The 12 panel drug testing screens a blood sample for up to twelve common drugs or drug classes, including prescription medications and illegal substances. It is ordered to check for recent drug use in medical, employment, or legal settings.

What it measures

  • Amphetamines — Stimulants such as Adderall or methamphetamine.
  • Barbiturates — Sedatives that can cause drowsiness.
  • Benzodiazepines — Anti-anxiety drugs like Valium or Xanax.
  • Cocaine — A stimulant that breaks down quickly in blood.
  • Opiates — Pain relievers like morphine or codeine.
  • THC (marijuana) — The active ingredient in cannabis.

Who it is for

A healthcare provider may order this test during a medical evaluation. Employers, courts, or other organizations may also require it.

Preparation

No fasting or special preparation is usually required. Tell the collector about any prescription or over-the-counter drugs you take, as they can affect results.

Results and what they mean

Results are reported as positive or negative for each drug panel, often within 1–3 business days. A clinician interprets them alongside your health history. This is general information, not medical advice; only a qualified professional can interpret your results.

How long do drugs stay in blood?
