A barbiturates screen is a blood test that looks for barbiturates, a class of sedative medications that slow brain activity. It is ordered when a person has symptoms such as extreme drowsiness, confusion, or slowed breathing, or when a clinician needs to check exposure to these drugs.

What it measures

  • Barbiturates (total) — A combined measurement of barbiturate drugs present in the blood.
  • Phenobarbital — A commonly prescribed barbiturate, often checked specifically.
  • Secobarbital — A short-acting barbiturate that may be included in the screen.
  • Pentobarbital — Another barbiturate sometimes detected by the test.
  • Amobarbital — A barbiturate that may be reported as part of the total.

Who it is for

The test is typically ordered by emergency clinicians, primary care providers, or toxicology specialists. It may also be requested by pain management or addiction medicine clinicians.

Preparation

No fasting or special preparation is usually required. Tell the clinician about all medications and supplements you take, since some can affect the result.

Results and what they mean

Results are reported as a level or as detected/not detected, depending on the lab. A clinician interprets the result alongside your symptoms, history, and other tests. This is general information only and is not medical advice; discuss your results with a qualified clinician.
