1. (a) Testing Standards. Substance testing is conducted in accordance with standards established by the Substance Abuse and Mental Health Service (SAMHSA), the Federal Motor Carrier Safety Administration (FMCSA). Alcohol testing is conducted using an evidential breath testing device and the method of determining the presence of a drug or substances is by collection and analysis of a urine sample. Employees may elect to provide a blood sample for either drug or alcohol testing.

2. (b) Screening and confirmatory tests for detection of drugs and substances.

   1. (1) For the purpose of testing, an initial screening test known as an immunoassay is performed. The screening test is used to eliminate negative urine specimens from further consideration and to identify the presumptively positive specimens that require confirmation or further testing.
   2. (2) For the purpose of testing, all specimens identified as positive on the initial test are confirmed positive by gas chromatography/mass spectrometry (GC/MS) before a positive result can be reported.
