How to read a certificate
- What each card shows. The control number and dates of the lot, then three results: label claim, heavy metals and microbiology. The PDFs hold the full detail.
- Label claim. Where an active was assayed on this lot, the bar shows the measured amount as a percentage of the label; other actives are listed at their formula amount.
- Tests on each card. Each card lists the results reported on that lot's certificate: label claim, heavy metals and microbiology.
- Key results. Cards marked Key results show the main results of the certificate for that lot; the PDF has the detail.
