The department may establish more than one method for use by testing laboratories and these standards may be developed through a reference laboratory.

(j)

1. (1) If a test result falls outside the specifications authorized by law or regulation, the testing laboratory shall follow a standard operating procedure to confirm or refute the original result.

2. (2) If a test result falls outside the specifications authorized by law or regulation, the testing laboratory may retest the sample if both of the following occur:

   1. (A) The testing laboratory notifies the department, in writing, that the test was compromised due to equipment malfunction, staff error, or other circumstances allowed by the department.
   2. (B) The department authorizes the testing laboratory to retest the sample.
