Standard Drug Testing Terminology

EBI’s Drug Testing Professionals have compiled a list of commonly used terms and definitions that appear in the Department of Transportation’s (DOT) rule, 49 CFR Part 40, which describes required procedures for conducting workplace drug and alcohol testing for the federally regulated transportation industry.  This glossary should not be considered to be all-inclusive nor is it intended to constitute legal advice.  It is especially important to consult legal counsel when making difficult decisions.  

 

Accession Number

A number assigned to each specimen by the laboratory.  This number stays with the specimen it's entire lifetime.  It is used to identify and track a specimen every step from the time it arrives to the laboratory until the result is reported.   

Adulterated Specimen

A specimen that contains a substance that is not expected to be present in human urine, or contains a substance expected to be present but is at a concentration so high that it is not consistent with human urine.   

Affidavit

A form that must be signed by the collector to correct a problem on the original Chain of Custody form.  For example, if the date was missing, incorrect, or the collector's signature was missing.   

Affiliate

Persons are affiliates of one another if, directly or indirectly, one controls or has the power to control the other, or a third party controls or has the power to control both.  Indicators of control include, but are not limited to: interlocking management or ownership; shared interest among family members; shared facilities or equipment; or common use of employees.  Following the issuance of a public interest exclusion, an organization having the same or similar management, ownership, or principal employees as the service agent concerning whom a public interest exclusion is in effect is regarded as an affiliate.  This definition is used in connection with the public interest exclusion procedures of Subpart R of this part.
