Certificates of Analysis


If an Expert Report is not required for court purposes, we can provide the results in the format of a Certificate of Analysis. This will list the drugs and analytes that we have analysed and indicate if they have been detected or not detected.

Certificates of Analysis are still reviewed and issued by our scientists and further interpretation in the form of an Expert Report can be requested at a later stage.
