Tests for Barbiturates
Barbiturates are a Schedule IV controlled substance available by prescription only but is also available on the illicit market. After oral administration, the onset of action takes from 15 to 40 minutes with lasting effects up to six hours.
Barbiturates are depressants that act as central nervous system and can produce a wide range of effects, from mild sedation to total anesthesia. Barbiturates also have analgesic effects. They have addiction potential, both physical and psychological. Barbiturates have now largely been replaced by benzodiazepines in routine medical treatment for anxiety and insomnia.
The drug testing kits below yield a positive result when Barbiturate metabolites in urine exceed 300 ng/mL. This is the suggested screening cut-off for positive specimens set by the Substance Abuse and Mental Health Services Administration (SAMHSA, USA).
