Benzodiazepines

Benzodiazepines are a large class of drugs used primarily for sedation and anxiety relief. Examples of Benzodiazepines include diazepam (Valium), chlordiazepoxide (Librium), alprazolam (Xanax), and clonazepam (Klonopin). Most benzodiazepine use in the US is due to prescription use, but some benzodiazepines are diverted for illegal consumption. Outside the US, particularly in Europe, benzodiazepines are more widely abused.

Benzodiazepines drug tests are one of the most popular types of drug test performed for pre-employment and random drug screening today. Benzodiazepines (sometimes called ‘benzos’) are also referred to as minor tranquillisers. They work by slowing down the activity of the central nervous system. They slow the messages going to and from the brain to the body, including physical, mental and emotional responses. Like alcohol, cannabis and heroin, they are depressants.


Technical Notes:

1. Common cross-reactants: To be determined. Of note, given the large number of benzodiazepine drugs (35+), be aware that GC/MS labs will not be able confirm for all of them.
2. NOT A SAMHSA-regulated drug, so cutoffs are usually country specific
3. Common US “screening� cutoff: 300 ng/mL
4. Some products/countries use 200 ng/mL screening cutoff
5. GC/MS confirmation cutoffs vary but usually range from 100-200 ng/mL
6. Again, GC/MS labs are limited by the number of benzodiazepines they identify on their GC/MS analyses
7. Medical Disposables distributes BZO - benzodiazepines drug test assays with cutoff levels of 300 and 200 ng/mL; both target oxazepam as the primary antigen.
