Frequently Asked Questions

Can I use a DIY method instead?

No. DIY tests and strips are prone to false results and cannot provide legally defensible data. Only certified THC-selective test methods can confirm the presence and level of contamination.

How long does testing take?

Testing itself should take only a short time, about 30 minutes or less. You’ll receive results within 10 business days after the lab receives your sample.

Is one kit enough?

For ease of interpretation, one test kit is recommended for a single surface, object or location. For multiple surfaces or locations, it is best to order a separate kit for each sample.

What’s included in each kit?

Each kit contains instructions, all sampling materials, chain-of-custody documentation and prepaid return shipping label. After the lab performs your analysis, you’ll receive a certified lab analysis, digital report, and access to quality customer service to address any follow-up questions.
