Why This Test Is Done

Your healthcare provider may order this test if they suspect recent use of triazolam, a prescription medication used to treat insomnia or anxiety. It could also be part of a broader evaluation for substance use, workplace safety checks, or legal reasons.

What to Expect Before the Test

No special preparation is needed. You’ll provide a 24-hour urine sample collected from the time you wake up in the morning until the next morning. Follow your doctor’s instructions carefully to ensure accurate results.

What the Test Results Mean

Positive results indicate recent triazolam exposure, while negative results mean it was not detected in your urine during the collection period. Results are qualitative (present or absent) and not used to determine dosage or duration of use alone.

Common Uses and Limitations

This test is primarily used for screening or confirmation of recent benzodiazepine use, not for monitoring ongoing treatment. It may miss recent use if the medication was taken shortly before the test or if it was metabolized quickly.

Clinical interpretation
