That said, providing timely accurate results is always the highest priority for our lab. Testing is performed as soon as the specimen arrives at our laboratory, however, the life of a drug testing specimen is filled with twists and turns. Other times a MRO is not needed and results are reported directly from the laboratory management system to the client. Results Reporting – In some circumstances results, regardless of the final result, are reported to a Medical Review Officer (MRO) who analyze the results before then releasing them directly to the client.– If the initial screening indicates a presumptive positive result, a specimen will undergo further confirmation testing. – If the screening results are negative, no further testing is needed. From there, all specimens go through an initial screening process which varies by specimen type.

Testing Process – After entering the laboratory, specimens are accessioned into the laboratory management system.Upon receipt, specimens are removed from their packaging, sorted by specimen type, and moved to the laboratory floor. Once they arrive at the unloading dock, they are considered “received” and enter processing. Arrival – Drug test specimens reach our laboratories through many different modes of transit.Our Quest Diagnostics drug testing laboratories measure turnaround time at three major timestamps throughout the process. It’s an important concept to understand and to factor into the selection of a drug testing provider, as on boarding new candidates and getting current employees back to work as quickly as possible is often of paramount importance. Turnaround time is a commonly used term to measure the duration of time it takes to return a positive or negative drug test result to the employer.
