Numbers need context. A report provides it.
Sample identity, methods, results and quantification limits: a guide to cannabis laboratory reports with an explicitly fictional example.
Check the sample identity
The sample identifier, product description, batch assignment and relevant dates should be traceable. Check who collected the sample and what was examined. A submitted sample does not automatically represent the whole batch.
Read the result together with the method
A result needs an analyte, unit, reference basis and method. Detection and quantification limits, and measurement uncertainty where reported, help interpretation. Ask the testing laboratory about missing information.
Establish comparability
Batch comparisons should use comparable sampling, matrices, units and methods. Different conditions can explain differences. A general statement such as ‘laboratory tested’ does not replace these details.
Not a blanket quality seal
A report documents its specific scope. Untested compounds remain unknown. Accreditation must relate to the specific body and scope; CannabisLabor.ch does not claim its own laboratory accreditation.

Fictional example · dried flower · THC-dominant profile
| Analyte | Demo value | Unit |
|---|---|---|
| Total THC | 22.25 | % m/m |
| THC | 1.20 | % m/m |
| THCA | 24.00 | % m/m |
| CBD | 0.10 | % m/m |
Total THC = THC + 0.877 × THCA, rounded. No real sample or medicinal product testing. No conclusion about safety, legality or product quality.
