Key Aspects of BZO Rapid Tests:
Purpose: Primarily used for preliminary screening in healthcare settings or, in specialized cases, for harm reduction (detecting drugs in substances).
Methodology: Uses immunological assays (often in strip or cassette format) to detect drug levels, usually with a 300 ng/mL cut-off.
Results: A negative result is indicated by two lines, while a positive result (indicating the presence of benzodiazepines) shows only one line in the control region.
Limitations: It is a screening tool, not a definitive diagnosis; positive results should be confirmed with more specific methods like Gas Chromatography/Mass Spectrometry (GC/MS).
Detection Window: In urine, benzodiazepines can typically be detected for 1–8 days, depending on the specific drug's half-life.

PROCEDURE
Bring tests, specimens and/or controls to room temperature (15‐30°C) before use.ꢀ
1. Bring the pouch to room temperature before opening it. Remove the test device from the sealed pouch and use it as soon as possible.
2. Place the test device on a clean and level surface. Hold the dropper vertically and transfer 3 full drops of urine (approx. 100 mL) to the specimen well (S) of the test device, and then start the timer. Avoid trapping air bubbles in the specimen well (S).
3. Wait for the colored line(C) to appear. Read results at 5 minutes. Do not interpret the result after 10 minutes.ꢀ
FAQ
Q:What shows up as BZO on a drug test?
A: Benzodiazepines (Urine)
Alprazolam.
Chlordiazepoxide.
Clonazepam.
Clorazepate.
Diazepam.
Lorazepam.
Oxazepam.
Q: What drugs fall under BZO?
A:Benzodiazepines (benzos) are a class of central nervous system depressants used to treat anxiety, insomnia, seizures, and muscle spasms, with common examples including Alprazolam (Xanax), Diazepam (Valium), Lorazepam (Ativan), Clonazepam (Klonopin), and Temazepam (Restoril), all working by enhancing the calming neurotransmitter GABA to slow brain activity.
Q: What are common reasons for taking a BZO test?
A: For example, if you are a victim of sexual assault, you may have this test to see if someone put a benzodiazepine date rape drug, such as flunitrazepam (Rohypnol or "roofie"), into your drink. You might also be tested if providers think you have taken benzodiazepines on accident or as a suicide attempt.
Q: How long does BZO stay in your urine?
A: Benzodiazepines can stay in urine from 1-2 days for short-acting types to 5-30 days for long-acting ones, with intermediate types typically lasting 1-5 days, but detection can extend for weeks with chronic heavy use, varying greatly by drug, metabolism, dosage, and frequency. Urine tests are common but may take hours to show positive after use as the drug needs to be processed by the body, making them less ideal for detecting extremely recent use, Mountain Valley Recovery.
Q: What is the cutoff level for BZO on a drug test?
A:
| Recommended Cutoff Levels for Initial Tests | |
|---|---|
| PCP* | 25 ng/ml |
| Benzodiazepines** | 100 ng/ml |
| Barbiturates** | 300 ng/ml |
| Methadone** | 300 ng/ml |
Q:Are benzos on the beers list?
A: The Beers criteria stipulate a maximum daily dose for short-acting benzodiazepines, with doses above the maximum considered potentially inappropriate.
