If you have any questions or concerns about one of our tests, we need to hear from you. We will be more than happy to discuss any issue you may have concerning any aspect of our process including traceability and determination of outliers.
Our objective is to design and operate our tests to provide the highest quality and value to our participant laboratories and their accrediting bodies. Artifacts are chosen to provide adequate range, uniformity and accuracy to provide tests that are easy to use and meaningful. Assigned values and measurement uncertainty are determined by using expert laboratories.
We take your concerns very seriously. We will address all complaints or appeals through our corrective action system. This will include investigation of cause, corrective action proposal and communication of the proposed resolution to concerned parties. PTI has an internal procedure P7.7.1 to handle all complaints and appeals.
Investigations and decisions on appeals do not result in any discriminatory actions.
