Read batch codes, dates, measurements and units in cannabis lab reports. A practical pre-purchase reading order.

A lab report becomes useful when it matches the correct batch and you understand what was tested. Read identity and dates first, scope and units next, then results. In the Club model each batch has a fresh, batch-specific report. Use this reading order with the original report for the batch offered.
1. Match report and batch
Find the report number, sample description and batch identifier. Compare them with the drop and product records. If a sample only has a cultivar name, request an unambiguous match. Keep the original file with the purchased batch records. A logo or cropped measurement does not replace the full report.
Keep reports and batch records connected2. Read dates and testing scope
Distinguish sampling, receipt, testing and issue dates where provided. A new issue date does not automatically mean a new sample. Check the actual tests listed. A cannabinoid profile answers different questions from residue or microbiological testing. Do not infer tests that the report does not name.
3. Compare results on the same basis
Check percentages, mg/g and the stated reporting basis. Mathematically, a mass fraction of 1% equals 10 mg/g. This is a unit conversion, not a product result or legal threshold. Do not casually compare dry-mass values with other bases, or a single substance with a reported total. Ask the issuing laboratory about unclear abbreviations.
4. Assess limits and unanswered questions
A result relates to the tested sample and stated scope. If uncertain, ask how that sample matches the offered batch. Accreditation concerns competence for specific activities; examine its scope rather than only a document logo. A fresh report alone does not guarantee every quality characteristic or establish a product’s marketability.
Your checklist
- Original report and clear batch match
- Sample and report dates distinguished
- Scope and units understood
- Questions resolved before buying
Common questions
Is a recent report date enough?
No. The actual sample, its link to the batch and the properties tested matter too. Different date fields can describe different events.
Where do I find an actual offer’s report?
Review the actual drop documents at CannabisClub.ch. Each batch in the described model has a fresh lab report. Use the original report and product information for that exact batch.
