Sec.  40.161  What does the MRO do when a drug test specimen is rejected for 

testing?

    As the MRO, when the laboratory reports that the specimen is 
rejected for testing (e.g., because of a fatal or uncorrected flaw), you 
must do the following:
    (a) Place a check mark in the ``Test Cancelled'' box (Step 6) on 
Copy 2 of the CCF and enter the reason on the ``Remarks'' line.
    (b) Report to the DER that the test is cancelled and the reason for 
cancellation, and that no further action is required unless a negative 
test is required (e.g., in the case of a pre-employment, return-to-duty, 
or follow-up test).
    (c) You may only report a test cancelled because of a rejected for 
testing test result when you are in possession of a legible copy of Copy 
1 of the CCF. In addition, you must have Copy 2 of the CCF, a legible 
copy of it, or any other copy of the CCF containing the employee's 
signature.
