A one-step test to detect barbiturates in human urine
Barbiturates are present in small amounts in almost all sedative and analgetic drugs. Their use in higher doses is in most cases a sign of a suicide attempt in case of adults and uncontrolled drug use in case of children. These are taken orally or by injection – i.v., i.m. Barbiturates are classified as fast acting (pentobarbital, secobarbital) – these act within 15 minutes, they metabolize in the body – and barbiturates effective within 24 hours and more (phenobarbital) – these leave the body in urine in an unchanged form. This a screening test, it is fast and accurate, it detects the presence of both barbiturate classes in human urine at concentrations above 300 ng/ml, even 4 days after drug use.
