Quality Assurance / Quality Control We maintain a QA/QC program to assure reliable results. We have certified standard reference materials for a variety of matrices and analytes, allowing us to provide better matching between reference material and samples. In some cases, we have alternate methods that can be used to confirm values obtained by our standard methods. We strive to make results that are very reliable, but we encourage customers to contact us if data does not meet expectations. Since quality is very important to us, we within reason, verify results at no additional charge. Quality control (QC) data is available as a part of your results. The data normally includes blanks, laboratory control samples (LCS), matrix spikes, and associated raw data.
