To assist in rapid identification of commonly abused drugs in suspected drug overdose or for workplace drug screening.
For ethanol, serum collected in a red-top tube; plasma collected in a gray-top (sodium fluoride/potassium oxalate) tube is also acceptable. For drug screen, urine collected in a clean plastic container. Gastric contents may also be submitted for testing.
Workplace drug-screening programs, because of the potential medicolegal consequences associated with them, require collection of urine and blood specimens using a chain of custody protocol. Analysis is performed in laboratories that are specially certified to perform workplace drug testing. The protocol provides securing the sample in a sealed transport device in the presence of the donor and a representative of the donor’s employer, such that tampering would be obvious. The protocol also provides a written document of specimen transfer from donor to specimen collection personnel, to storage, to analyst, and to disposal.
