Testing Types

Each participant must submit to:

  1. An annual test;
  2. One or more random* tests; and
  3. Reasonable cause or post-accident/incident tests as needed.
*Selection for random tests is through Computer Generated Selection (GGS). The random selection is 25% per local per year. A participant may be random-tested multiple times a year or not at all.


All tests are solely for drug and alcohol screening and cannot be used for any other screening or identifying medical information. Only the Designated Representative (DR) will receive confidential information from the TPA.
