Analysis Services

When ordering testing from Green Leaf Lab, you will choose a state compliance package or multiple individual tests exceeding state requirements to apply to your harvest lot or process lot batches. The analysis descriptions below provide details of the analysis service, and note when the particular analysis service may be required.

Individual Analyses

Pesticide Analysis

Pesticide testing compliant to OAR 333-007-0400 Exhibit A, Table 3 is required for marijuana, usable marijuana and concentrates and extracts. See OAR 333-007-0320 and OAR 333-007-0330 and OAR 333-007-0390.

OHA Temporary Rule Update December 2, 2016 through May 30, 2017

  • 333-007-0360(1)(d): A portion of samples taken from multiple batches of usable marijuana may be combined for purposes of testing for pesticides if the multiple batches in total do not exceed ten pounds. If the combined samples fail for pesticides ALL the batches fail.

OHA Temporary Rules for OLCC Recreational Producers and Wholesalers March 2, 2017 – August 28, 2017
Temporary pesticide testing rules previously effective September 30, 2016 through March 1, 2017 have been extended through August 28, 2017 by the Oregon Health Authority. From batches within the same harvest lot, the rule allows reduced pesticide testing – only one-in-three batches from the harvest lot are required to be sampled for pesticide compliance.

At least one batch in each harvest lot must be tested, and at least 1/3 of the total quantity must be tested. Requirements are summarized in the table below.

Harvest lot size in pounds Number of 10lb batches required for pesticide testing Number of 10lb batches required for all other testing
0-10 1 1
11-30 1 3
31-60 2 6
61-90 3 9
91-120 4 12

The temporary reduction in pesticide testing requirements is based on OHA findings of insufficient licensed laboratory pesticide capacity statewide.

  • 333-007-1000(1): Notwithstanding OAR 333-007-0300 to 333-007-0490 and 333-064-0100, until March 1, 2017, if the Commission finds there is insufficient laboratory capacity for the testing of pesticides, the Commission may permit randomly chosen samples from batches of usable marijuana to be tested for pesticides by a licensed laboratory rather than requiring every batch of usable marijuana from a harvest lot to be tested for pesticides.

Potency Analysis

This test is required for edibles, flower, extracts and concentrates, tinctures and topicals. See OAR 333-007-0320 through 333-007-0345.

Residual Solvent Analysis

The list of residual solvents required to be tested for has been updated as of December 2, 2016. For the updated list of solvents required for extracts and concentrate testing, see temporary rules published and effective, December 2, 2016 through May 30, 2017; OAR 333-007-0410 Table 4.

Terpene Analysis Add On

This test is not required by the State. Green Leaf Lab has a new dedicated instrument used only for testing terpenes. The terpene add-on pricing must include a potency or compliance test.

See our terpene education page for more information about why you may order a terpene profile analysis.

Water Activity

This test is required for usable marijuana. If a sample has a water activity rate of more than 0.65Aw, the sample fails. See OAR 333-007-0420.

Moisture Content

This test is required for usable marijuana. If a sample has a moisture content of more than 15 percent, the result must be reported to the licensee, but the sample does not fail. See OAR 333-007-0420

Mold

Mold testing is not required by the state, but is a service available from Green Leaf Lab.

Ordering a mold test will demonstrate that you use production techniques that ensure the highest quality cannabis flower. Mold analysis ensures product safety, especially for medical marijuana that may be dispensed to patients with weakened health.

Oregon dispensary law previously set a mold and mildew limit of 10,000 CFU/g.

State Compliance Packages

Usable Flower Compliance

Includes the following tests required by the state: potency, pesticide, water activity, and moisture content. This test package is required for all OMMP growers who want to bring their product to dispensaries. This test package is also required for OLCC licensed producers. See OAR 333-007-0320.

Extract/Concentrate Compliance

This testing includes potency, pesticide, and residual solvent testing. This test is required for all concentrate and extract products.

Temporary rules published and effective December 2, 2016 through May 30, 2017 have deleted butanol, propanol, and ethanol from the original list OAR 333-007-0400 Exhibit A, Table 4. For the updated rules, see temporary rules OAR 333-007-0410 table 4.

Control Study (for Processors)

As of the temporary rules effective December 2, 2016 through May 30, 2017, a control study has replaced process validation. A product must successfully complete one control study annually. Any changes to processing method require a new control study. A control study must pass the required tests for the particular product, and must not exceed a relative standard deviation of more than 30% for either residual solvents or potency. See temporary rules effective December 2, 2016 through May 30, 2017 Exhibit B, OAR 333-007-0360 Table 5 for cannabinoid concentrates, extracts and products, except cannabinoid edibles and Table 6 for cannabinoid edibles. See charts below.
