Chapter 15 - Drug Testing Programs in Job Related Accident Cases
Section I-1503 - Scientific and Technical Requirements

A. Compensation shall not be allowed to the employee who receives personal injury from a job-related accident if the injury was caused by the employee's intoxication. Compensation will not be precluded, however, where the intoxication resulted from activities which were in pursuit of the employer's interest or in which the employer procured the intoxicating beverage or substance and encouraged its use during the employee's work hours. When an employee receives personal injury from an accident arising out of and in the course of his employment, his employer may test the employee for alcohol, and for any drug identified in Schedules I, II, III, IV or V of 21 U.S.C. 812.

B. Definitions

Aliquot- a portion of a specimen used for testing.

Confirmatory Test- a second analytical procedure used to identify the presence of a specific drug or metabolite in a specimen. The confirmatory test must be different in technique and chemical principle from that of the initial test procedure to ensure reliability and accuracy. [At this time gas chromatography/mass spectrometry (GC/MS) is the only authorized confirmation method. Gas chromatography is authorized for confirmation of alcohol (ethanol) concentrations in specimens.]

Initial Test- a sensitive, rapid, and inexpensive immunoassay screen to eliminate true negative specimens from further consideration.

Intralaboratory Chain of Custody- procedures used by the laboratory to maintain control and accountability from the receipt of specimens until testing is completed, results reported, and while specimens are in storage.
