May the MRO report an “interim” or “preliminary” test result to the employer (or C/TPA) while awaiting receipt of the MRO copy and/or the laboratory result?

• No. An MRO must not report tests results until and unless he or she has received all required information from the collection site and laboratory. 

• This means the MRO must have Copy 2 or a legible copy of Copy 2 (or any legible copy of a CCF page signed by the employee) and must have the drug test result (sent in the appropriate manners for negatives and non-negatives) from the laboratory. 

• An MRO sending “in-progress” negative or non-negative results will be considered to be in violation of Part 40.
