Collectors are a very important part
of a drug-testing program. The Division of Workplace Programs has
published a Urine Specimen Collection Handbook that provides additional
guidance to supplement the requirements in the Mandatory Guidelines for
Federal Workplace Drug Testing Programs.
Private employers may want to use it
as a guide. A collector that is trained and knows what to look for
regarding the possible techniques used by donors to defeat a drug test
should minimize the number of specimens that are adulterated or
substituted.
The most important precautions a
collector can take to minimize the opportunity an employee would have to
adulterate or substitute a urine specimen are:
(1) Ensure that the employee does not
have access to anything at the collection site that could be used to
adulterate or substitute a urine specimen; and
(2) Request the employee to remove
and display any items he or she may have concealed in pockets, coats,
hat, etc.
