Sec. 40.109  What documentation must the laboratory keep, and for how

    (a) As a laboratory, you must retain all records pertaining to each 

employee urine specimen for a minimum of two years.

    (b) As a laboratory, you must also keep for two years employer-

specific data required in Sec. 40.111.

    (c) Within the two-year period, the MRO, the employee, the employer, 

or a DOT agency may request in writing that you retain the records for 

an additional period of time (e.g., for the purpose of preserving 

evidence for litigation or a safety investigation). If you receive such 

a request, you must comply with it. If you do not receive such a 

request, you may discard the records at the end of the two-year period.
