Specimen:

Urine

Collection Medium:

Minimum:

10 mls random urine

Testing Schedule:

Analytic Time:

2 hours (upon receipt in laboratory)

Reference Range:

None

Comments:

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

Confirmation automatically sent to a commercial laboratory for 
amphetamines, barbiturates, cocaine and opiates, except for patients in 
the ETC or from Eldora Juvenile Home.  Confirmation for opiates is also 
NOT automatic for any inpatient units.

Confirmation of any test is accomplished by the ordering physician 
calling Specimen Control at 356-3527, upon receipt of a positive 
screening result. The samples are maintained in the laboratory frozen 
for 30 days post screening.

Confirmation is at an additional charge.

Methodology:

Online DAT automated assays are based on the kinetic interaction of 
microparticles in a solution (KIMS) as measured by changes in light 
transmission.
