A barbiturate screen and confirmation checks blood for barbiturate drugs, which are sedatives that slow brain activity. It is ordered when a person has symptoms like confusion or extreme drowsiness, or as part of a drug monitoring program. The screen gives a quick answer, and the confirmation verifies any positive result.

What it measures

  • Barbiturate screen — A rapid test that shows whether any barbiturate may be present.
  • Confirmation test — A more precise method that identifies the specific barbiturate and its amount.
  • Specific barbiturates — Examples include phenobarbital, secobarbital, and pentobarbital.

Who it is for

Doctors order this test for people with unexplained sedation, confusion, or a known or suspected overdose. It may also be used in monitoring during treatment for barbiturate use.

Preparation

No special preparation, such as fasting, is usually needed. Tell the person drawing your blood about any medicines you take, because some can affect the test.

Results and what they mean

Results are reported as positive or negative for the screen, and the confirmation lists which barbiturate was found and its level. A clinician interprets these results along with your symptoms and history. This is general information, not medical advice; talk with a healthcare professional about your results.
