Urine Testing
Detection periods for barbiturates vary greatly depending on the specific barbiturate being used. Each barbiturate has a different half-life in the body, meaning they stay around for different periods of time. Shorter acting barbiturates (Allobarbital, Alphenal, Amobarbital, Aprobarbital, Butabarbital, Butalbital, Butethal, Pentobarbital, Secobarbital) can be detected for only 1 to 4 days, while long-acting barbiturates (Barbital, Phenobarbital) can be detected for 2 to 3 weeks.

Substances or Conditions which can cause false positives
Dilantin, Fiorinal, and Fioricet. Fiorinal and derivatives are often prescribed for migraines and chronic tension headaches.
