We've made changes to our Certificates


We've recently upgraded our certificates with a new look. None of the data have changed, but the way they are arranged on the page is now as follows

The only two cannabinoid numbers required to be present on the package label are Total THC and Total CBD, also known as THCmax and CBDmax, respectively. These numbers have the largest font of all the numbers on the certificate. In the footer, there is a description of how the totals are calculated.

Please be aware that the Traceability system recently added a new value called "Total Cannabinoid" which is an incorrect name for the value associated with it. "Total Cannabinoid" as reported in Traceability is actually just a sum of THCmax and CBDmax. In contrast, the "Total Cannabinoid" value reported by Confidence is a raw sum of all cannabinoids measured and is intended to represent the raw weight of cannabinoids in the sample. Biotrack has admitted their mistake in naming the value "Total Cannabinoids" and we have been told they are working on changing the name to something like "THC+CBD". Again, what Biotrack calls "Total Cannabinoid" is actually just THCmax + CBDmax.

Due to recent changes to the Traceability system, there are sometimes slight discrepancies between the totals listed in Traceability and totals measured by the lab. This is another bug in the Biotrack software, and is due to slight rounding differences between their software and ours. We are not going to change the way our software calculates totals, because our values are the correct values, and indeed the law states that the values reported by the lab on the Certificate of Analysis are the official values. The differences in rounding never affect more than the last digit of the value, which is only 1/10th of one percent or less, so the actual impact is rather small.

We hope these updates to our certificates will help to make it more readable and presentable. As always, we appreciate feedback.

Proposed Rule Changes For Testing and Labeling


Following recommendations by the QA Work Group (an LCB sponsored think-tank composed of labs, producers, processors, retailers, WSDA, DOH, DOE, and outside interest groups) the LCB has proposed some major revisions to the rules related to testing and labeling.

Revisions to the testing rules are far overdue. These revisions represent the culmination of serious effort by many stakeholders to improve the testing paradigm in our industry.

Below is a synopsis of the proposed changes

  • Increase maximum lot size to 15 lbs
  • Sample the population such that variance can be described. See Sampling Cannabis for Analytical Purposes to learn more.
  • Require ISO Certification for all Cannabis Labs
  • Revision of microbial limits test
  • Require reporting of acidic cannabinoids
  • Enhancing the Residual Solvent Test
  • Pesticide testing at the harvest level instead of lot level
  • Allowing wholesale without testing if the product is intended for extraction
  • Allowing labs to reference each other
  • Allowing retests without specific LCB approval (automated retesting)
  • Defining lot remediation

Confidence Analytics does have a seat on the QA Work Group, and has been actively involved in advocating for our clients. We have been soliciting feedback from the community, and we welcome your feedback. If you have issues related to the testing rules that you’d like us to bring to the conversation, please email nick@conflabs.com

Based on feedback we’ve received so far, the following is a synopsis of further revisions we are advocating for:

  • Lift the cap on lot size to allow for infinite lot size (per-strain per-harvest, not arbitrary ceiling)
  • Reduce the number of required potency tests from what is being proposed
  • Remove ethanol limits from residual solvent list
  • Allow for process validation to demonstrate homogeneity of batch
  • Remove microbiological screening requirement for solvent-based extracts
  • Require package labeling of any non-cannabis-derived-additive in vaporizable products

These changes are likely to make our testing industry more transparent, more repeatable, and more honest. Such dramatic changes will not come quick. It will be at least 4 months before a CR103 is filed and these rules become effective. In the meantime, if you have recommendations please get in touch. Your lab is advocating for you.

Want to Test it Yourself?


Have you ever wanted to do your own analytical testing onsite at your production/processing or retail facility? Have you tried some of the handheld and/or infrared testing devices only to find that they aren't very accurate? We've got a solution for you:

Confidence Analytics is selling one of our HPLC-DAD instruments. This is the gold standard in cannabinoid analytics, and you could have one at your operation. We are selling the full-stack including: autosampler, mixer, degasser, quaternary pump, thermostated column compartment, diode array detector, computer and chemstation controller software. We can also provide reagents, consumables, calibration, method, training and support to use the instrument for precision cannabinoid analysis on a routine basis. We'll show you how it works!

It's an Agilent 1100 Series HPLC. A very capable and versatile instrument that is built to last and has been well maintained. We are replacing it with a newer model, and no longer have need for it. The instrument has and continues to perform well, having tested over 10,000 cannabis samples successfully... and counting.

It is calibrated for THC, CBD, CBG, the acid forms of all three, CBC, and CBN, and you could add others at your expense. It is capable of testing flower and concentrates with a method that is reasonably straightforward. Edibles and topicals are also doable, through require more operator training, scientific savvy, reagent use, and equipment maintenance.

You won't be able to use the instrument for QA testing in traceability, unless your business is accredited as a cannabis laboratory. Otherwise, it would be for onsite R&D testing purposes only. Please call to inquire.

Now Testing Medical Harvests


Confidence Analytics is now equiped to test for medical harvests under the new DOH rules.

Please call to inquire.

Sample Size and Protocol. LCB Rule Change.


The WSLCB enacted a set of emergency rules to take effect on June 18th, 2016, which includes a sample size minimum for flower of 4 grams. The rule also describes requirements for randomization of sample selection, more details can be found on our website, and the WSLCB's Recently Adopted Rules under "-2015 Marijuana Legislation Implementation (Effective June 18, 2016)."

To avoid delaying results, please be ready to provide 4 gram samples by June 18th.

Confidence Analytics is Now Testing for Pesticides.


After manufacturer installation, onsite validation to factory specifications, extensive calibration and method development, and a lot fo hard work, Confidence Analytics is proud to offer the Northwest a highly advanced technology capable of detecting pesticides and drug compounds of interest with extreme sensitivity. Read more on our Pesticide FAQ page.

The WSLCB's recent emergency rules describe action levels for pesticide residues, whereby detection above these levels could be cause for a recall. The rules do not mandate pesticide testing, nor do the rules mandate reporting of pesticide test results. Until further rules are enacted, pesticide testing is optional and neither the laboratory nor the recipient of the data is required to report the results to anyone.

Now is your window to find out what your baseline pesticide levels are before mandatory testing and reporting become a reality. If you are a processor who makes concentrates, you should consider spot checking some of your starting material.
