Specimen:

Urine

Collection Medium:

Minimum:

10 mls random urine

Testing
Schedule:

24 hrs/day, 7 days a week, including holidays.

Analytic Time:

2 hours (upon receipt in laboratory)

Reference Range:

None

Comments:

Screen includes amphetamines, metamphetamines, barbiturates, 
benzodiazepines, cocaine, phencyclidine, opiates, 
tetrahydrocannabinoids (THC) and urinary tricyclic antidepressants.
A positive result for any of the tested drugs indicates the presence of 
the drug or metabolites in the urine, but does not measure the level of 
intoxication.

Confirmation automatically sent to a commercial lab for 
amphetamine/methamphetamine, barbiturates, cocaine, opiates and 
phencyclidine.  Call UIDL Client Services, 1-866-844-2522, if 
confirmation of benzodiazepines or tetrahydrocannabinoids is needed.  
The samples are maintained in the laboratory frozen for 30 days post 
screening.

Suggested confirmation of urinary tricyclic antidepressants is by the 
serum tricyclic antidepresssant screen test performed by Clinical 
Chemistry.
