Reporting Results of a Double Specimen Collection During a Single Testing Event (Immediate Directly Observed Collection)

Description

It may be necessary to perform a second, directly observed specimen collection during a Department of Transportation (DOT) mandated urine specimen collection. This will result in two results which may be significantly different and which therefore may be confusing to an employer. The Medical Review Officer (MRO) should report the results in a way that reduces the chances for a misunderstanding.

Situations when an immediate directly observed collection is performed:

(1) temperature out of range

(2) evidence of specimen tampering

Possible results for each specimen:

(1) negative

(2) non-negative (any combination of adulterated, substituted and/or positive)

Result on Initial Specimen	Result on Directly Observed Specimen	Results Reported
negative	negative	directly observed reported, initial held (not reported)
negative	non-negative	directly observed reported, initial held (not reported)
non-negative	negative	initial reported, directly observed held (not reported)
non-negative	non-negative	both results reported
