URINE BARBITURATE*

This assay is useful in detecting drug abuse to Barbiturates which are commonly used as "Downers" to induce sleep after Amphetamine or Cocaine induced "High". As most Barbiturates are fast acting, their presence indicates use within the past 3 days except Phenobarbital which has a longer half life and its presence in urine indicates drug usage within the last 30 days.
