This urine test screens for benzodiazepines and confirms any presumptive positive result. Benzodiazepines are a class of sedative drugs that includes alprazolam, flurazepam, lorazepam, nordiazepam, and oxazepam. Combining a screening immunoassay with a specific confirmation method helps distinguish true benzodiazepine exposure from cross-reactivity and supports clinically reliable reporting. Testing both the screen and the confirmation together supports clearer reporting in clinical, workplace, and monitoring settings.

• Benzodiazepines (screen) The drug class detected by immunoassay, including compounds such as alprazolam, lorazepam, and oxazepam.
• Benzodiazepine confirmation A specific analysis such as chromatography with mass spectrometry used to verify and identify the benzodiazepine present.

• A clinician suspects benzodiazepine use and wants a verified result.
• You are in a monitoring program requiring urine drug testing.
• You take a prescribed benzodiazepine and its presence needs documentation.
• A legal or employment screening requires confirmation of any screen positive.

• No fasting is required for this urine test.
• Provide a fresh sample at the collection site.
• Report all anti-anxiety medications, sedatives, and sleep aids.
• Avoid excessive fluids before collection to keep the sample concentrated enough for testing.

A negative result suggests benzodiazepines were not detected above the cutoff. A presumptive positive is confirmed by the second method, which can identify which benzodiazepine, such as alprazolam or oxazepam, is present. Detection time in urine depends on the specific drug and its half-life. Because sedative findings can have clinical and legal implications, review the confirmed result with a healthcare provider.
