Reporting Procedures

Sample price includes a comparison report listing our assigned value and the laboratory’s value which may include different detectors, shelves, etc. Upon data submission to our web portal, you will receive a report immediately. The known values along with client values are tabulated with the ratios of the known to reported values. Since data quality objectives vary among laboratories, no pass/fail criteria are used unless requested in advance.
