Benzodiazepines(BZO) Panel Test is used for in vitro quantitative detection of Benzodiazepines content in human urine. Benzodiazepines are medications that are frequently prescribed for the symptomatic treatment of anxiety and sleep disorders.  Risk of physical dependence increases if Benzodiazepines are taken regularly (e.g, daily) for more than a few months, especially higher than normal doses. Stopping abruptly can bring on such symptoms as trouble sleeping, gastrointestinal upset, feeling unwell, loss of appetite, sweating, trembling, weakness, anxiety and changes in perception.
