Medical Cannabis Testing FAQs

 

How much sample is required for testing?

How much does testing cost?

What is your turn around time?

I'm a first-time customer. What do I need to bring with me to set up an account?

Do my flowers need to be cured or can they be fresh?

If you are looking for Potency only, we require 1 gram of flower, 0.1 g of concentrate or 2 grams of edible.

Full panel analysis for all materials requires at least 5 grams.

We require a copy of your grower or processor license in paper or electronic format.  We will attach this to your account for future visits.  You may also email us a copy before your visit for convenience.  We also require a copy of a driver's license for first time drop offs of any person transporting your samples.  This is for everyone's protection especially when relinquishing processed samples back to you.

Cured samples only.  If they are fresh, there is a high chance for failure on Water Activity.

We strive to process the full panel analysis in 5-7 business days.  Potency testing currently happens 2 to 3 times a week depending on how many samples we receive.  The earlier in the week you bring your samples, the faster you will receive results as certain tests require several days to process fully.  Microbiological tests are currently set up Monday and Tuesday.

Please contact a member of our team regarding pricing.  We are working to make a price list as soon as requirements are finalized with the State of Oklahoma.

Bulk discounts for multiple samples are available. Rush analysis for potency is available but discouraged as it will incur a 100% upcharge.

What are your business hours?

We are open from 8 AM to 5 PM, Monday through Friday.

I'm a medical marijuana patient.  Do you test samples for individuals as well?

Yes. We require that you bring your Patient Identification Card and driver's license the first time you bring samples.

I signed up for an online account.  Why am I not able to log in?

Each online account is manually reviewed by a member of our staff to ensure safety of your data.  This can take up 48 hours depending on what time we received your request.

I have a farm and would like my soil and water tested as well.  Do you do that?

We have been an environmental testing laboratory for 15+ years.  GCT is TNI accredited by the NELAC Institute as well as the OKDEQ.

Do you have pickup or sampling services available for cannabis?

At this time, we cannot transport cannabis.  All cannabis samples will need to be hand delivered to the laboratory.

Can I get my potency results in mg per my own measurement?

If you would like your tinctures or oils in mg form rather than in wt%, we can do so if you let us know how much the dose weighs in grams. For example, if your serving size is 1 teaspoon, the we would need to know how much one teaspoon of your material physically weighs.
