What this test is
A barbiturate screen and confirmation, urine test uses an initial immunoassay to detect barbiturates or their breakdown products in a urine sample. If the screen is positive, a more specific confirmation method is used to verify the result. This two-step process reduces the chance of a false positive.
What it measures
- Barbiturate screen — detects the presence of barbiturate-class drugs or their metabolites in urine
- Confirmation result — identifies and verifies specific barbiturates if the screen is positive
- Creatinine (sometimes included) — helps assess whether the urine sample is dilute
What the test involves
You provide a urine sample, typically collected in a private restroom at the lab or collection site. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to check for recent barbiturate use as part of a medication monitoring plan, a workplace or legal requirement, or an evaluation for possible overdose. It is also used when symptoms suggest sedative exposure.
Preparation
No special preparation is usually required, but you should follow the collection lab's instructions. Tell the lab about any medications or supplements you take, as some may affect the test.
How results are reported
Results are reported as negative or positive for the screen, with confirmation results identifying specific barbiturates if present. Reference ranges and cutoffs vary by laboratory, so your results should be interpreted in the context of the lab's own criteria.
