Barbiturates Confirmation, Chain of Custody, Random, Urine
Use
This test is useful for detecting drug abuse involving barbiturates such as amobarbital, butalbital, pentobarbital, phenobarbital, and secobarbital. The chain of custody is required whenever the results of testing could be used in a court of law. The purpose is to protect the rights of the individual by demonstrating that the specimen was always under control and limited the opportunity for tampering.
Special Instructions
Not provided.
Limitations
There are no significant cautionary statements. However, the presence of barbiturates in urine indicates use within a certain time frame. Most barbiturates are fast-acting with presence indicating use within 3 days. Phenobarbital might indicate use within the past 30 days due to its long half-life.
