CoA - Certificate of analysis

Tryp Labs CoA interpretation

So, you just got a certificate of analysis (CoA), either from your own sample submission, or shared by a friend. Now you might be thinking, what am I looking at? Let’s look at one of these CoA’s and break it down.

A CoA is a printout of results of a laboratory analysis. At the top of the CoA, it is common to see the laboratory that analyzed the sample, the agent that submitted the sample, the date, and the type of analysis. Below those, you can find information about the sample, like the name, the sample type (i.e., mushroom, edible, tincture, extract, etc.), the date it was received and processed, and how much sample was used.

Typically, the next section shows the results of the analysis in a table format. Within the results table, the analyte is any chemical that is analyzed. In a Tryp Labs CoA, the analytes are listed on the column on the far left. To the right, these are quantified as two different numbers, milligram per gram (mg/g) and percent by weight (%w). The milligram per gram unit refers to how many milligrams of the analyte are present in a gram of the sample, while the percent by weight is the percentage of the weight of the sample that is the analyte. The result is the same for each analyte but reported as two different units. This may be helpful depending on what unit you are typically used to reading.
