TEST TYPES #
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.
FALSE POSITIVES #

Dilantin, Fiorinal, and Fioricet. Fiorinal and derivatives are often prescribed for migraines and chronic tension headaches.
CAUTION & DISCLAIMER #
Erowid's drug testing information is a summary of data gathered from site visitors, journal articles, websites, and other resources. Detection periods depend on amount and frequency of use, metabolic rate, body mass, age, overall health, drug tolerance, and urine pH of each individual. Many substances that are not tested for in basic or extended urinalysis tests CAN be tested for by a laboratory willing to go to the trouble, although that is uncommon.
