Q: How long do I have to dispute a result?

A: USDTL saves negative specimens for seven days after initial accessioning. Seven days is longer than the customary three days that most labs retain negatives. This duration should allow clients a reasonable time to decide if dispute resolution is needed, to contact customer service and initiate the process. Positive specimens are stored frozen for one year following accessioning. Our Client Services Representatives will provide you with the necessary paperwork for you to sign and return to initiate the re-test process. Once the paperwork is in order, Client Services will return a re-test result to you in one to two working days. If you have any questions after receiving the results, please contact Client Services and they will either assist you or direct you to one of our forensic toxicologists to discuss the case with you.
