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

    (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.
