Speed can be a critical component of a workplace drug testing program. How much faster? Looking at the past three years of data, drug test specimens collected at PSCs yield final test results on average about 4 hours faster than specimens collected at sites not owned and operated by Quest Diagnostics. To combat these uncontrolled variables, we recommend using a collection site within our Patient Service Center (PSC) network for faster, more consistent turnaround times. For instance, if the collection takes place at the employer’s location or at a collection site outside of the Quest Diagnostics collection site network, we have little to no control over the transportation logistics of that specimen or the accuracy of the collection time. Once the specimen leaves a collection site, factoring logistics into the turnaround time equation can be complex. As soon as the collection is complete, the specimen and any necessary documentation is packaged and shipped to the laboratory.ĮCCF case study: Paper is the past, step into digital drug testing with eCCF Many collection sites are electronically enabled, allowing them to complete collections using an electronic chain of custody form (eCCF), which saves paper and generates more accurate timestamps. Our collectors are trained to follow standardized processes at every location to help control the integrity of the specimens and the drug test results. Yet when the specimens are not within our direct supervision, obtaining an accurate measurement becomes more challenging.īefore coming to the lab, the first step in the drug test specimen lifecycle – the collection – can significantly influence turnaround times. Calculating turnaround time while specimens are within the walls of our laboratories is relatively simple to determine. 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.
