What it measures
A check for benzodiazepines, a group of sedative and anti-anxiety medicines such as diazepam, or their breakdown products, in a urine sample. Screens pick up some benzodiazepines more readily than others.
Why people test it
- Checked to show no recent use, for example for work, during recovery or for personal reasons.
- Part of wider drug screens that test for several drugs from one urine sample.
Typical range
Reported as detected or not detected (positive or negative) against a cut-off level. Cut-offs vary by lab and the report shows the lab's own; a positive screen is often confirmed by a second, more specific lab method.
Finger-prick or vein?
A urine sample rather than blood, given at a clinic or with a home kit. How long a drug stays detectable depends on the drug, the amount and how often it is used.
Benzodiazepines taken on a prescription, such as diazepam, show on this screen in the same way.
