How to Submit Samples to MB Labs

Updated

MB Labs accepts sample drop-offs at its Sidney, BC laboratory Monday through Friday, 8:30 a.m. to 4:30 p.m. Pacific Time; the lab is closed Saturday and Sunday. To submit a sample, you bring it to 2062 West Henry Ave, Sidney BC, along with basic information about the sample and the tests you want. The standard way to provide that information is the Chain of Custody Form, which identifies who you are, the sample description and lot number, and the testing you are requesting.

Before You Go

Confirm a few things first so your drop-off isn't delayed:

  • Testing category. MB Labs offers services across Water & Environmental, Food Safety, Cannabis & Hemp, and Agricultural testing. Knowing which category your sample falls under helps you request the right tests.
  • Test selection. The Chain of Custody Form asks what tests you want, so decide this before arriving.
  • Sample identification. Have your sample description and lot number ready — these go on the form.
  • Timing. Arrive between 8:30 a.m. and 4:30 p.m. PT on a weekday. The lab does not accept drop-offs on weekends.

Step-by-Step: Dropping Off a Sample

  1. Get the Chain of Custody Form. MB Labs provides this form under its Tools & Information section. The lab describes it as the normal way people submit samples — not just for cannabis — because it captures your identity, the sample description and lot number, and the requested tests.
  2. Complete the form. Fill in who is submitting the sample, what the sample is (including lot number), and which tests you need.
  3. Bring the sample and form to the lab. Deliver them in person to 2062 West Henry Ave, Sidney BC, during the Monday–Friday 8:30 a.m.–4:30 p.m. window.
  4. Provide any additional basic information requested. MB Labs notes that some basic information is required at drop-off beyond the form itself.

Expected result: Once accepted, your sample enters the lab's analytical and testing process, and results are reported back to you. MB Labs publishes guidance under "Interpreting Your Results" if you need help reading what comes back.

If You're Unsure About Anything

The lab's own guidance is to contact them directly rather than guess:

This is the right move if you don't know which test category applies to your sample, aren't sure how much sample to bring, or need the current Chain of Custody Form.

Common Snags

  • Arriving outside hours. The 8:30 a.m.–4:30 p.m. PT window is firm, and weekends are closed.
  • Incomplete form. Missing your identity, sample description/lot number, or requested tests means the lab can't process the submission as intended.
  • Wrong test category. Picking tests that don't match your sample type can waste a trip — call ahead if unsure.
