Can the MRO require an employee’s split specimen test request to be in writing rather than verbal?

• 40.171(a) states that the employee’s request may be verbal or in writing. Therefore, the MRO must accept a verbal request. 

• The MRO may ask the employee for written documentation, but must immediately honor the verbal request. 

• An MRO should always document whether or not an employee requested to have the split tested. 

• The MRO must document the date and time of the employee’s request.
