Rule 5 CCR 1005-5-10 - Hemp Testing Laboratories: Certificate of Analysis (COA)
10.1 The laboratory shall generate a Certificate of Analysis (COA) for each Sample that the laboratory analyzes.
10.1.1 The COA shall indicate that the reported results are for compliance testing purposes for all samples analyzed.
10.2 The laboratory shall ensure that the COA contains the results of all requested analyses performed for the Sample.
10.3 The laboratory shall, within 1 business day of completing Total THC analysis of a Sample, provide a copy of the COA to the submitting Industrial Hemp Cultivator and the Colorado Department of Agriculture Hemp Regulatory Program.
10.4 The COA shall contain, at minimum, the following information:
10.4.1 Laboratory's name, address, and contact information;
10.4.2 Hemp Cultivator's or Hemp Manufacturer's name, address, and USDA licensee number if applicable;
10.4.3 Sampler identification;
10.4.4 Sample identifying information, including Matrix type and unique Sample identifiers, including lot identification number when applicable;
10.4.5 Sample received date, and the date(s) of Sample analyses and corresponding testing results;
10.4.6 Units of measure;
10.4.7 The analytical methods, analytical instrumentation used, and corresponding Limits of Detection (LOD) and Limits of Quantitation (LOQ);
10.4.8 For Samples of Hemp, identification of a pre-harvest or post-harvest retest (i.e., remediated) when applicable.
10.4.9 For Samples of Hemp, reported cannabinoid results must include the range of estimated uncertainty which shall be reported as a ± value in the same units of measure as the test result, following best practices for significant figures and rounding; and
10.4.9.1 For Samples of Hemp, reported cannabinoid results must provide a calculated Total THC value + uncertainty on a dry weight basis.
10.4.10 A dedicated area to include any qualifiers or comments needed for interpretation, (when applicable to the test method and results being reported) to include any identified and documented discrepancies.
10.4.11 The COA may contain additional information at the discretion of the laboratory and submitting client.
10.5 The laboratory shall report test results for each representative Sample on the COA as follows:
10.5.1 When reporting qualitative results for each Analyte, the laboratory shall indicate presence or absence;
10.5.2 When reporting quantitative results for each Analyte, the laboratory shall only report results that are above the lowest concentration of calibrator or standard used in the analytical run;
10.5.3 When reporting results for any Analytes that were detected below the analytical method LOQ and above the LOD, indicate "<LOQ";
10.5.4 When reporting results for any Analytes that were not detected or detected below the LOD, indicate "ND" or "<LOD"; and
10.6 The laboratory director or supervisory analyst shall validate the accuracy of the information contained on the COA.
