Once your results have been processed and entered into LEAF, you will receive an automated email with the COA attached.


Our typical turnaround time is three to four days, depending on the panel, with most results coming out in three days.

Two-day rushes are available upon request. Please contact us for more details.


Unfortunately, we are no longer able to provide LR codes to our clients.

According to an email sent out from the WSLCB by Kendra Hodgson, Cannabis Examiner Manager, on May 1, 2020, to all Marijuana Licensees, Approved Third Party Integrators, and Certified Labs:

his message is to provide clarity regarding a repeated LCB request for labs to provide the Lab Result (LR) code to licensees and third-party commercial integrators. Please note that the LR code is not the test results themselves, but the unique software identifier connected to the lab record that is generated when a lab enters the test results.

To date we have verbally instructed labs and third-party integrators that this is not an approved practice as it undermines the integrity of the labs results.

WAC-314-55-102 (2)(a) states the following…

To support this reporting requirement, the state’s traceability system was designed to facilitate the reporting of test results directly from labs to the state.

The Certificate of Analysis provided is a direct reflection of the results entered into Leaf by certified marijuana labs. It also serves to support the licensee testing and record keeping requirements. In no way is the Certificate of Analysis or related system identifier (LR Code) to be used to apply results to other product or edit existing results.

WSLCB has received numerous requests to authorize the release of the LR Code to licensees and third party integrators. We are also aware that labs are now being approached directly with this request. The request has been reviewed and denied. As there have been no business needs presented to overturn the policy decision that do not undermine the integrity of the test results, labs do not have authorization from the WSLCB to release the Leaf System LR code.

Thank you for your attention to this important matter.
