Certificate of analysis
NAD+
Every released batch of NAD+, with the analytical record that released it. Figures are the laboratory's measurements — where the label and the assay disagree, the assay is the number to calculate from.

Testing standards
The references applied
Compendial standards govern how each determination is made and what limit it is judged against. Naming them is what allows a result to be compared with one produced elsewhere.
